Long‐Wavelength Light‐Induced Group 13–15 Elementalization Reactions of Alkenes/Alkynes

Abstract

We present di‐ tert ‐butyl peroxide (DTBP)‐catalyzed long‐wavelength light‐induced Group 13, 14, and 15 elementalizations of alkenes and alkynes, through in situ production of tert ‐butyl radicals, followed by a hydrogen‐atom‐transfer process generating silyl, germyl, stannyl, alkyl, boryl, and phosphoryl radicals. This mild and photosensitizer‐free methodology employing blue (450 nm)/green (530 nm)/orange (600 nm) LEDs affords high chemoselectivity and broad functional group tolerance compared to conventional use of shorter‐wavelength light. Synthetic, spectroscopic, and computational data are consistent with a vibration‐mediated photolysis mechanism of DTBP involving electronic excitation from vibrationally excited ground states (S ₀ μ _n ) to the excited state (S ₀ μ _n →S _n transitions), driven by ultraweak absorption of long‐wavelength visible light.

Photosensitizer-free infrared-light-induced radical reactions

Antônio Junio Araujo Dias, Ken Tanaka, Masanobu Uchiyama, Yuki Nagashima

　More details

Publisher：American Chemical Society (ACS)

Infrared (IR) light is a source of mild energy that facilitates selective chemical reactions in a deeply penetrative manner. However, harvesting IR light through electronic excitation is challenging, and thus organic photoreactions at wavelengths over 1000 nm are scarce even with specialized photosensitizers. Herein, we report radical reactions driven by IR-A (~1000 nm) or IR-B light (~1500 nm) via vibration-mediated photolysis in the absence of a photosensitizer. The developed method promotes diverse transformations, including iodination, alkylation, and selenation reactions, with wider scope, higher selectivity, and deeper penetration through reaction media, compared with those of conventional irradiation with visible light. Applications include irradiation through obstacles, one-pot sequential transformations, and flow chemistry in opaque tubing. Experimental and spectroscopic studies reveal that the absorption of IR light via vibrational modes promotes photolysis that triggers radical chain reactions.

ABSTRACT

Transition metal (TM)‐catalyzed photoreactions have emerged as powerful tools for synthesizing products that are challenging to obtain under conventional thermal conditions. However, most protocols rely on short‐wavelength visible light, such as purple or blue light (<500 nm). Although long‐wavelength light (>500 nm) allows for milder conditions, higher chemical selectivity, and deep light penetration, its application in single TM‐catalyzed photocatalytic systems is rare. Herein, we present the long‐wavelength visible‐light‐accelerated Rh(III)‐catalyzed olefination of arenes bearing an anilide moiety as a directing group. This methodology circumvents the use of external photosensitizers and short‐wavelength blue light, owing to the use of a cationic Rh(III) complex. Experimental and computational analyses suggest that the Rh(III) complex initially acts as a C─H activation catalyst, and oxidation of the generated Rh(III) hydride intermediate by oxygen is accelerated by absorption of long‐wavelength visible light (> 500 nm).

Rhodium‐Catalyzed Intermolecular Arylative [2 + 2 + 1] Annulation–Oxidation to Produce Electron‐Deficient Azulene‐Embedded Polycyclic Aromatic Hydrocarbons

Abstract

Azulene derivatives have attracted much attention for their application in organic electronic materials and devices because of their large dipole moment and small HOMO–LUMO energy gap. As these physical properties of azulene depend on its substitution and condensation patterns, developing methods to synthesize functionalized and π‐extended azulenes is desirable. However, synthesizing π‐extended azulenes requires harsh reaction conditions, making it hard to achieve both functionalization and π‐extension. Here, we report the synthesis of electron‐deficient azulene‐embedded polycyclic aromatic hydrocarbons (PAHs) with two alkoxycarbonyl groups by the rhodium‐catalyzed intermolecular arylative [2 + 2 + 1] annulation of teraryl diynes with dialkyl acetylenedicarboxylates followed by oxidation at room temperature. Interestingly, for the electron‐rich diyne, prolonged oxidation time after the arylative [2 + 2 + 1] annulation yields a helicene‐like bis(azulene‐embedded PAH) in good yield. Thus, obtained electron‐deficient fused azulenes have small HOMO–LUMO energy gaps (up to E _g ^elec = 1.52 and E _g ^theo = 2.06), resulting in long‐wavelength absorption extending into the near‐infrared region. Due to bulky electron‐withdrawing groups and π‐extension, the molecule becomes saddle‐shaped and highly polarized, and strong π–π stacking interactions are observed in both the solid and solution states.

We have developed the Rh‐catalyzed enantioselective [2+2+2] cycloaddition of homopropargyl enamides (tosylamide‐tethered 1,6‐enynes) with alkynes to construct tetrahydroindole skeletons found in natural alkaloids and pharmaceuticals. This cycloaddition proceeds at room temperature in high yields and regio‐ and enantioselectivity with a broad substrate scope. The preparative scale reaction followed by substituent conversion on the nitrogen atom and the diastereoselective [4+2] cycloaddition with singlet O2 affords hexahydroindole‐diols bearing three stereogenic centers and variable substituents on the nitrogen. Mechanistic studies have revealed that the substituents of the enynes change the ratio of intramolecular and intermolecular rhodacycle formation when using terminal alkynes, varying the ee values of the cycloadducts.

Vibration-mediated long-wavelength photolysis of electronegative bonds beyond S0–S1 and S0–T1 transitions Reviewed International journal

Abstract

Photolysis is an attractive method in organic synthesis to produce free radicals through direct bond cleavage. However, in this method, specific irradiation wavelengths of light have been considered indispensable for excitation through S₀–S_n or S₀–T_n transitions. Here we report the photoinduced homolysis of electronegative interelement bonds using light at wavelengths much longer than theoretically and spectroscopically predicted for the S₀–S_n or S₀–T_n transitions. This long-wavelength photolysis proceeds in N–Cl, N–F, and O–Cl bonds at room temperature under blue, green, and red LED irradiation, initiating diverse radical reactions. Through experimental, spectroscopic, and computational studies, we propose that this “hidden” absorption is accessible via electronic excitations from naturally occurring vibrationally excited ground states to unbonded excited states and is due to the electron-pair repulsion between electronegative atoms.

Dearomative construction of multiply‐fused 2D/3D frameworks, composed of aromatic two‐dimensional (2D) rings and saturated three‐dimensional (3D) rings, from readily available quinolines has greatly contributed to drug discovery. However, dearomative cycloadditions of quinolines in the presence of photocatalysts usually afford 5,6,7,8‐tetrahydroquinoline (THQ)‐based polycycles, and dearomative access to 1,2,3,4‐THQ‐based structures remains limited. Herein, we present a chemo‐, regio‐, diastereo‐, and enantioselective dearomative transformation of quinolines into 1,2,3,4‐THQ‐based 6‐6‐4‐membered rings without any catalyst, through a combination of nucleophilic addition and borate‐mediated [2+2] photocycloaddition. Detailed mechanistic studies revealed that the photoexcited borate complex, generated from quinoline, organolithium, and HB(pin), accelerates the cycloaddition and suppresses the rearomatization that usually occurs in conventional photocycloaddition. Based on our mechanistic analysis, we also developed further photoinduced cycloadditions affording other types of 2D/3D frameworks from isoquinoline and phenanthrene.

The synthesis, characterization, and catalytic performance of an iridium(III) catalyst with an electron-deficient cyclopentadienyl ligand ([CpEIrI2]2) are reported. The [CpEIrI2]2 catalyst was synthesized by complexation of a precursor of the CpE ligand with [Ir(cod)OAc]2, followed by oxidation, desilylation, and removal of the COD ligand. The electron-deficient [CpEIrI2]2 catalyst enabled C-H amidation reactions assisted by a weakly coordinating ether directing group. Experimental mechanistic studies and DFT calculations suggested that the high catalytic performance of [CpEIrI2]2 is due to its electron-deficient nature, which accelerates both C-H activation and Ir(V)-nitrenoid formation.

Transition metal photo-induced catalysts operating in a single catalytic cycle are preferable compared with binary catalytic systems comprising both transition metal and photoredox catalysts. Such single-catalyst systems perform the dual function of visible light absorption and chemical transformation. However, most visible-light-driven catalytic reactions proceed via radical mechanisms, limiting the reaction types to which the catalysts are applicable. Several non-radical catalytic reactions have been developed, but these reactions are substrate dependent owing to the low visible-light-harvesting ability of the catalysts. Here we report the design, synthesis and visible-light-induced non-radical reactions of dual-functional Rh catalysts, spiro-fluorene-indenoindenyl (SFI)-Rh(I) complexes. The SFI-Rh(I) complexes with non-fused but π-extended ligands reduce substrate dependence owing to high visible-light-harvesting ability, and show high stability due to resistance against protonation. Thus, the SFI-Rh(I) catalysts extend the scope of typical Rh(I)-catalysed reactions, such as the C–H borylation of arenes and [2+2+2] cycloaddition of alkynes, to challenging substrates under blue light-emitting diode irradiation at room temperature.

Abstract

Organoboron and organosilicon compounds are used not only as synthetic building blocks but also as functional materials and pharmaceuticals, and compounds with multiple boryl and silyl groups are beginning to be used for these purposes. Especially in drug discovery, methodology providing easy stereoselective access to aliphatic nitrogen heterocycles bearing multiple boryl or silyl groups from readily available aromatic nitrogen heterocycles would be attractive. However, such transformations remain challenging, and available reactions have been mostly limited to dearomative hydroboration or hydrosilylation reactions. Here, we report the dearomative triple elementalization (carbo-sila-boration) of quinolines via the addition of organolithium followed by photo-boosted silaboration, affording the desired products with complete chemo-, regio-, and stereoselectivity. The reaction proceeds via the formation of silyl radicals instead of silyl anions. We also present preliminary studies to illustrate the potential of silaboration products as synthetic platforms.

Trivalent group-9 metal catalysts with a cyclopentadienyl-type ligand (CpMIII; M = Co, Rh, Ir, Cp = cyclopentadienyl) have been widely used for directed C-H functionalizations, albeit that their application to challenging C(sp3)-H functionalizations suffers from the limitations of the available directing groups. In this report, we describe directed C(sp3)-H amidation reactions of simple amide substrates with a variety of substituents. The combination of an electron-deficient CpERh catalyst (CpE = 1,3-bis(ethoxycarbonyl)-substituted Cp) and an electron-deficient 2-pyridone ligand is essential for high reactivity.

A rhodium(III) complex bearing a 1,3-bis(ethoxycarbonyl)-substituted or an unsubstituted cyclopentadienyl ligand (CpE or Cp) significantly accelerates a variety of oxidative C–H bond functionalization reactions. However, the driving force of the acceleration compared with a conventionally used Cp*Rh(III) complex has not been elucidated. Herein, we performed density functional theory (DFT) calculations of the rhodium(III)-catalyzed oxidative C–H bond olefination and annulation reactions using Cp*, Cp, and CpE ligands, which revealed that the CpERh(III) complex stabilizes transition states of not only a C–H bond activation step but also rate-determining reductive elimination and insertion steps by strong orbital interactions. For the sterically demanding substrates, the less sterically hindered CpRh(III) complex can stabilize the transition states of the reductive elimination step more than the CpERh(III) complex. Moreover, the whole reaction pathways were calculated to elucidate the mechanism and selectivity of the oxidative [4 + 2] and [2 + 2 + 2] annulation reactions under cationic and neutral conditions, respectively.

Planar chiral zigzag-type [8]- and [12]cyclophenylene (CP) belts have been synthesized in good yields with high ee values of 98% and 83%, respectively, by the rhodium-catalyzed enantioselective intramolecular sequential cyclotrimerizations of the corresponding cyclic polyynes. The observed high enantioselectivity arises from the regioselective formation of a rhodacycle intermediate from an unsymmetric triyne unit. The X-ray crystal structural analysis of the racemic planar chiral zigzag-type [8]CP belt revealed that the uneven molecules mesh with each other to form a one-dimensional columnar packing structure, in which one column contains single enantiomers, giving two types of chiral columns [(S)- and (R)-form columns] arranged alternately. The ring strain of the zigzag-type [8]CP belt was smaller than that of the armchair-type [8]CPP belt despite its smaller ring size, due to the presence of the strain-relieving m-terphenyl moieties. The effect of the number of the benzene rings of the zigzag-type CP belts on absorption and emission peaks was small due to interruption of π-conjugation at the m-phenylene moieties. However, the bending effect on the absolute fluorescence quantum yield as well as absorption and emission peaks was significant. Concerning chiroptical properties, the modest anisotropy dissymmetry factors of ECD and CPL were observed in the [8]CP belt.

An S-shaped double helicene-like molecule (>99 % ee), possessing stable helical chirality, has been synthesized by the rhodium(I)/difluorphos complex-catalyzed highly diastereo- and enantioselective intramolecular double [2+2+2] cycloaddition of a 2-naphthol- and benzene-linked hexayne. The collision between two terminal naphthalene rings destabilizes the helical chirality of the S-shaped double helicene-like molecule, but the introduction of two additional fused benzene rings significantly increases the configurational stability. Thus, no epimerization and racemization were observed even at 100 °C. The enantiopure S-shaped double helicene-like molecule forms a trimer through the multiple C-H⋅⋅⋅π and C-H⋅⋅⋅O interactions in the solid-state. The trimers stack to form columnar packing structures, in which neighboring stacks have opposite dipole directions. The accumulation of helical structures in the same direction in the S-shaped double helicene-like molecule enhanced the chiroptical properties.

The smallest spherical carbon nanocage so far, [2.2.2]carbon nanocage, has been synthesized by the cationic rhodium(I)/H8 -binap complex-catalyzed regioselective intermolecular cyclotrimerization of a cis-1-ethynyl-4-arylcyclohexadiene derivative followed by the triple Suzuki-Miyaura cross-couplings with 1,3,5-triborylbenzene and reductive aromatization. This cage molecule is highly strained, and its ring strain is between those of [6] and [5]cycloparaphenylenes. A significant red-shift of an emission maximum was observed, compared with that of known [4.4.4]carbon nanocage. The sequential cyclotrimerizations of a cis-1,4-diethynylcyclohexadiene derivative with the same rhodium(I) catalyst followed by reductive aromatization failed to afford [1.1.1]carbon nanocage; instead, a β-graph-shaped cage molecule was generated.

A belt-shaped [8]cycloparaphenylene (CPP) and an enantioenriched Möbius-shaped [10]CPP have been synthesized by high-yielding rhodium-catalyzed intramolecular cyclotrimerizations of a cyclic dodecayne and a pentadecayne, respectively. This Möbius-shaped [10]CPP possesses stable chirality and isolated with high enantiomeric purity. It is evident from the reaction Gibbs energy calculation that the above irreversible cyclotrimerizations are highly exothermic; therefore establishing that the intramolecular alkyne cyclotrimerization is a powerful route to strained cyclic molecular strips.

Abstract The effect of substituents on carbamoylmethyl?cyclopentadienyl (CpA) ligands on the neutral rhodium(III)?catalyzed oxidative [4+2] annulation of indole? and pyrrole?1?carboxamides with alkynes, in which the C?H bond cleavage is the partially rate?limiting step, was investigated. As a result, in the reactions with terminal alkynes, a rhodium(III) complex with a dimethyl?substituted CpA ligand (CpA3) showed high catalytic activity and improved the regioselectivity as compared to a commercially available Cp*RhIII complex. On the other hand, in reactions with internal alkynes, a rhodium(III) complex with a diphenyl?substituted CpA ligand (CpA1 or CpA2) showed high catalytic activity, which is comparable to the activity of the Cp*RhIII complex. Interestingly, a rhodium(III) complex with an electron?deficient di(ethoxycarbonyl)?substituted Cp ligand (CpE) that shows high catalytic activity toward the annulation of benzamides with internal alkynes, in which the C?H cleavage is rate?limiting, showed low catalytic activity toward the reactions with both terminal and internal alkynes. The ligand effects above provide important guidelines for the application of our CpA and CpE ligands to the rhodium(III)?catalyzed C?H bond functionalization reactions.

The cover picture shows the Japanese famous inverted image of Mt. Fuji (reflected in the water). The scheme shows the general catalytic cycle of the transition-metal-catalyzed cyclization of alkynals via oxametallacycle intermediates. This cyclization is a highly efficient method for the stereoselective synthesis of carbocycles and heterocycles. This reaction is catalyzed by Ni, Rh, Ru, and Ti complexes and mediated by organometalloid reagents (X-Y = Si-H, B-C), organometallic reagents (X-Y = Zn-C), dihydrogen (X-Y = H-H), and org. reagents (X-Y = C-H, C-P). Details are presented in the Microreview by K. Tanaka and Y. Tajima on p. 3715 ff. [on SciFinder(R)]

Language：English Presentation type：Poster presentation

Transition-metal-catalyzed hydroalkynylative cross-trimerizations of terminal alkynes with unsatd. compds. are highly efficient and atom-economical methods for the synthesis of alkynyl-substituted linear carbon scaffolds. The trimerization of three different unsatd. compds. is the challenging theme due to the difficulty of the chemo-, regio- and stereoselectivity control. Esp., a synthesis of conjugated enynes by the coupling of terminal alkynes, alkynes, and alkenes has not been reported to date. Herein, we report a cationic rhodium(I)-catalyzed linear cross-trimerization of silylacetylenes, alkynyl esters, and electron-deficient alkenes giving conjugated enynes. [on SciFinder(R)]

今年度は、以下に示す研究を実施し有益な知見を得た。カチオン性ロジウム(I)／軸不斉ビアリールビスホスフィン錯体触媒を用いた分子内不斉[2+2+2]付加環化反応により、高度なねじれと歪みを有する鞍型シクロフェニレン誘導体の合成を目指し、原料となるポリインの合成とその分子内不斉[2+2+2]付加環化反応を検討した。その結果、パラジウム触媒を用いたアリールハライドとアルキンとの分子間薗頭・萩原カップリング反応と、炭酸カリウムを塩基として用いるフェノール誘導体とプロパリジルブロミドとの分子間エーテル結合生成反応により、原料となるポリインの合成に成功した。そして、得られたポリインの分子内不斉[2+2+2]付加環化反応により高度なねじれと歪みを有する鞍型シクロフェニレン誘導体の合成に成功した。しかし、様々な検討を行なったが単結晶の作成には成功しておらず、単結晶X線結晶構造解析による構造確認が課題である。このシクロフェニレン誘導体はこれまでに合成例のないトポロジー（キラリティー）を有しており、この触媒的不斉合成は大きな意義をもつ研究成果であると考えている。

The synthesis of [8]cycloparaphenylene octacarboxylate and [6]cycloparaphenylene tetracarboxylate was achieved by the stepwise chemo- and regioselective [2+2+2] cycloaddition reactions of diynes with symmetrical electron deficient internal alkynes using a cationic rhodium (I)/H8-BINAP catalyst and subsequent reductive aromatization. The structures and packing modes of these compounds were clarified by X-ray crystal structure analyses. In addition, we successfully synthesized a precursor of a branched cycloparaphenylene by the complete intermolecular homo-[2+2+2] cycloaddition reaction. Furthermore, we succeeded in developing the new cycloaddition reactions, which would be employed as a key reaction in the synthesis of various cyclic pi-conjugated molecules.

In recent years, non-planar extended pi-conjugated compounds have attracted great attention because of their unique physical properties and functions originated from steric distortion and chirality. However, due to the large distortion and steric hindrance of these compounds, the synthesis of designed new compounds is often challenging. Therefore, in this study, we examined the development of new highly active transition-metal complexes as catalysts and their application to the synthesis of novel non-planar extended pi-conjugated compounds. As a result, we succeeded in synthesizing various new non-planar extended pi-conjugated compounds (helicenes, cyclophanes, cycloparaphenylenes, etc.). We also succeeded in their catalytic asymmetric syntheses and chemical modifications that allow their organization and assembling.

当研究グループは、カチオン性Rh錯体触媒を用いた [2+2+1]環化三量化反応によるシリルフルベンの合成を報告した。しかし、かさ高い置換基を有する電子不足アルキンを用いると、ヒドロアルキニル化反応生成物であるエンインと、さらにもう一分子のシリルアセチレンと反応した鎖状三量化反応生成物である共役ジエンインが得られた。そこで詳細な条件検討を行った結果、カチオン性Rh錯体触媒存在下、シリルアセチレン/電子不足アルキン/電子不足アルケン鎖状三量化反応が良好な収率で進行した。また、カチオン性Rh/BINAP錯体触媒存在下、ナフトール架橋1,6-エンインとアルキンを反応させると、ロダシクロペンテン中間体からのβ-酸素脱離を経由して生成したと考えられる、3-ビニルナフトフラン誘導体が生成することを見出した。詳細な条件検討の結果、カチオン性Rh/BINAP錯体触媒を80-90℃で作用させると、3-ビニルナフトフラン誘導体が良好な収率で得られた。また当研究グループは、N-アリールアルキニルアミドの分子内不斉ヒドロアリール化反応を報告した。本反応において、1-ナフチル基を有するN-アリールアルキニルアミドを基質としカチオン性Pt(II)触媒作用させると、二つの炭素―炭素結合生成を伴う触媒的脱芳香環化反応が進行した。さらに当研究グループは、カチオン性Rh(I)錯体触媒を用いると、アリルプロパルギルエーテルのオレフィン異性化、プロパルギルクライゼン転位、及びカルボニル転位反応がワンポットで進行することを報告した。続いて、エンインのアリル基近傍に二重結合を有するジエンインにカチオン性Rh錯体触媒を作用させることで、最高5種類の異なる機構の反応を含む新規カスケード反応が良好な収率で進行した。

本研究では、カチオン性ロジウム/BINAP系錯体触媒を用いた不斉[2+2+2]付加環化反応に、合成容易かつ安定なヘテロ原子で置換されたアルキンを用いることにより、1)芳香環の構築、2)芳香環へのヘテロ原子導入、3)軸不斉のエナンチオ選択的構築、の3つをワンステップで達成可能とする、新規軸不斉配位子の革新的不斉合成法の開発を検討した。その結果、カチオン性ロジウム/BINAP系錯体触媒存在下、α,ω-ジインとアシルホスホネートとの[2+2+2]付加環化反応によるジエニルホスホネート合成、及び1,6-ジインと1,3-ジイン構造を有するジホスホネートとの不斉[2+2+2]付加環化反応による軸不斉ビアリールジホスホネートの高エナンチオ選択的合成に成功した。また、カチオン性ロジウム/BINAP系錯体触媒存在下、1,6-ジインとN,N-ジアルキルアルキニルアミドを反応させることにより、安定な軸不斉を有するN,N-ジアルキルベンズアミド誘導体の高エナンチオ選択的合成にも成功した。さらに、カチオン性金錯体触媒を用いた新規なヘテロ環構築法として、N-アルケニルアルキニルアミドの環化異性化反応による置換ピリドン合成にも成功した。

我々は最近、カチオン性ロジウム/二座ホスフィン錯体が付加環化反応やσ結合活性化反応等の極めて優れた触媒となることを見出し、多数の触媒的炭素-炭素及び炭素-ヘテロ原子結合生成反応を開発した。更に、これらの新規触媒反応の不斉触媒反応への展開にも成功した。今回これらの反応に、反応基質あるいは第二の配位子としてカルボニル化合物を用いると、1)アルデヒドとアクリルアミド誘導体を用いた新規分子間ヒドロアシル化反応、2)2-ビニルベンズアルデヒドや2-アルキニルベンズアルデヒドと、ア夕リルアミド誘導体、ジカルボユル化合物、及びアシルホスホネートとの形式的分子間不斉[4+2]付加環化反応、3)5-アルキナールの様々な触媒的骨格異性化反応、4)ジインあるいはエンインとジカルボユル化合物、及びジインとアシルホスホネートとの触媒的分子間不斉[2+2+2]付加環化反応、5)アリールケトン、ベンズアミド、及びアクリルアミド誘導体のオルト位C-H結合活性化反応を経由する、アルキンへの触燃的ヒドロアリール化及びヒドロアルケニル化反応、6)エナミドとa,ω-ジインとの不斉[2+2+2]付加環化反応、7)アルケンとジアルキルアセチレンジカルボン酸エステルとの共二量化及び不斉共三量化反応、8)第二の配位子としてエノール化可能な環状ジカルボニル化合物を用いた、α、ω-ジインのトリェンヘの新規環化異性化反応、等の様々な新しい協奏的な分子触媒反応が進行することを見出した。

シクロファンはその特異な構造から、基礎から応用に至るまで幅広い研究が行われてきたが、その合成は多段階かつ低収率であるため、標価化合物の供給が著しく困難であった。当研究室では昨年、Rh(I)^+/H8-BINAP錯体を用いた、カーボンリンカーを有するα,ω-ジインとアセチレンジカルボン酸ジメチルエステル(DMAD)の分子間環化三量化反応による、[7]-[12]パラカルバシクロファンの合成を報告した。この反応にポリエーテルα,ω-ジインを用いたところ、[7]-[21]ポリエーテルシクロファンの合成に成功した(Eur.J.Org.Chem.投稿中)。また当研究室では昨年、Rh(I)^+/(R)-H8-BINAP錯体触媒を用いた、ポリエーテルリンカーを有する対称内部ジインとアセチレンジカルボン酸ジ-t-ブチルエステルとの分子間環化三量化反応により、面不斉[7]-[9]メタポリエーテルシクロファンの合成を見い出した。更なるエナンチオ選択性の向上を目指し検討を行ったところ、本反応にRh(I)^+/(S)-DM-H8-BINAP錯体触媒を用い、高濃度(0.2M)で反応を行うことにより、エナンチオ選択性の向上に成功した。また、中間体の構造制御を目的とし、ポリエーテルリンカーを有する内部トリインの分子内環化三量化反応を検討したところ、Rh(I)^+/(R)-H8-BINAP錯体触媒を用いることにより、面不斉[6]-[9]メタポリエーテルシクロファンが高いエナンチオ選択性で得られた(J.Am.Chem.Soc.投稿中)。更に、このアルキンの不斉分子間環化三量化反応にイナミドを用いることにより、アトロプ異性アニリドのエナンチオ選択的合成を達成した(J.Am.Chem.Soc.2006)。
