これまで、面不斉を有するヘテロ中員環化合物は、全く報告されていなかった。これに対し、我々は、中員環ジアリルアミン類が室温下安定な面不斉を有することを初めて見出した(例えば、特許文献1参照、または非特許文献1参照)。また我々は、これら面不斉分子が、光学活性な含窒素環状化合物の不斉合成素子として有用であることも明らかにしている(例えば、非特許文献2参照)。

So far, no hetero-medium ring compound having surface asymmetry has been reported. On the other hand, we found for the first time that medium ring diallylamines have stable surface asymmetry at room temperature (for example, see Patent Document 1 or Non-Patent Document 1). We have also clarified that these planar asymmetric molecules are useful as an asymmetric synthesis element of an optically active nitrogen-containing cyclic compound (for example, see Non-Patent Document 2).

(試験1)ハロゲンを有する中員環ジアリルアミド1の合成(R=トシル、R=水素、X=ヨウ素)
9員環ジアリルアミド1は、対応するラクタムから4工程で調製した。対応するラクタムにDIBALを作用させ、ヘミアミナールとした後、α−ヨードホスホン酸エステルを用いたHorner−Wardsworth−Emmons反応によりエステルを調製した。このエステルにDIBALを作用させ、アミドアルコールを得た。次に、このアミドアルコールの分子内光延反応を行った。アルゴン雰囲気下0℃にて、トリフェニルホスフィン(105.9mg,0.4038mmol)とアゾジカルボン酸ジエチル(0.17mL,40wt%トルエン溶液)のTHF溶液(5mL)に、アミドアルコール(53.1mg,0.115mmol,>95%dr)THF(5mL)溶液を滴下した。反応溶液を、0℃で11時間40分撹拌後、徐々に室温まで昇温し、室温で2時間20分撹拌した。その後、溶媒を除去し、カラムクロマトグラフィー(ヘキサン/酢酸エチル=10/1から5/1)にて精製したところ、目的の9員環ジアリルアミド1が収率87%で得られた。合成した1は、キラルカラムHPLC分析の結果、積分比1対1の2成分に分割することができ、面不斉の存在が確認できた。また、キラルカラムHPLC分取より光学活性体として得ることができた。
(Test 1) Synthesis of medium-membered ring diallylamide 1 having halogen (R 1 = tosyl, R 2 = hydrogen, X = iodine)
The 9-membered diallylamide 1 was prepared from the corresponding lactam in 4 steps. DIBAL was allowed to act on the corresponding lactam to form a hemiaminal, and then an ester was prepared by a Horner-Wardsworth-Emmons reaction using α-iodophosphonate. DIBAL was allowed to act on this ester to obtain amide alcohol. Next, an intramolecular Mitsunobu reaction of this amide alcohol was performed. To a THF solution (5 mL) of triphenylphosphine (105.9 mg, 0.4038 mmol) and diethyl azodicarboxylate (0.17 mL, 40 wt% toluene solution) at 0 ° C. under an argon atmosphere, amide alcohol (53.1 mg, 0.115 mmol,> 95% dr) in THF (5 mL) solution was added dropwise. The reaction solution was stirred at 0 ° C. for 11 hours and 40 minutes, then gradually warmed to room temperature, and stirred at room temperature for 2 hours and 20 minutes. Thereafter, the solvent was removed and the residue was purified by column chromatography (hexane / ethyl acetate = 10/1 to 5/1). As a result, the desired 9-membered diallylamide 1 was obtained in a yield of 87%. As a result of chiral column HPLC analysis, the synthesized 1 could be divided into two components having an integration ratio of 1: 1, and the presence of surface asymmetry could be confirmed. Moreover, it was able to be obtained as an optically active substance from chiral column HPLC fractionation.

(試験2)芳香環を有する中員環アミド2の合成(R=トシル、R=メチル、Y=水素)
芳香環を有する中員環アミド2は、ジオールから5工程で合成した。ジオールに別途調製した。N−トシルメトキシカーバメイトを光延反応により、位置選択的に導入し、アルコールを調製した。その後、アルコールを酸化し、アルデヒドとした後、Horner−Wardsworth−Emmons反応により、エステルを調製、その後DIBAL還元により、環化前駆体であるアミドアルコールを得た。次に、このアミドアルコールの分子内光延反応を行った。アルゴン雰囲気下、−78℃にて、トリフェニルホスフィン(44.0mg,0.1678mmol)とアゾジカルボン酸ジエチル(76.1mL,40wt% トルエン溶液)のTHF溶液(8.5mL)に、アミドアルコール(37.7mg,0.1049mmol,dr=72/28)THF(2mL)溶液を滴下した。反応溶液を、0℃まで昇温した。その後、溶媒を除去し、カラムクロマトグラフィー(ヘキサン/酢酸エチル=10/1から2/1)にて精製したところ、目的の9員環アミド2が収率75%(monomer/dimmer=93/7)で得られた。合成した2は、キラルカラムHPLC分析の結果、積分比1対1の2成分に分割することができ、面不斉の存在が確認できた。また、キラルカラムHPLC分取より光学活性体として得ることができた。
(Test 2) Synthesis of medium ring amide 2 having an aromatic ring (R 3 = tosyl, R 4 = methyl, Y 1 = hydrogen)
Medium ring amide 2 having an aromatic ring was synthesized from diol in 5 steps. Prepared separately in diol. N-tosylmethoxycarbamate was regioselectively introduced by Mitsunobu reaction to prepare alcohol. Thereafter, the alcohol was oxidized to an aldehyde, and then an ester was prepared by a Horner-Wardsworth-Emmons reaction, followed by DIBAL reduction to obtain an amide alcohol as a cyclization precursor. Next, an intramolecular Mitsunobu reaction of this amide alcohol was performed. Under an argon atmosphere at −78 ° C., THF solution (8.5 mL) of triphenylphosphine (44.0 mg, 0.1678 mmol) and diethyl azodicarboxylate (76.1 mL, 40 wt% toluene solution) was added to amide alcohol (8.5 mL). 37.7 mg, 0.1049 mmol, dr = 72/28) A THF (2 mL) solution was added dropwise. The reaction solution was heated to 0 ° C. Thereafter, the solvent was removed and the residue was purified by column chromatography (hexane / ethyl acetate = 10/1 to 2/1). As a result, the desired 9-membered cyclic amide 2 was obtained in a yield of 75% (monomer / dimer = 93/7). ). As a result of chiral column HPLC analysis, synthesized 2 could be divided into two components having an integration ratio of 1: 1, and the presence of surface asymmetry could be confirmed. Moreover, it was able to be obtained as an optically active substance from chiral column HPLC fractionation.
