    名称:
    Total synthesis of optically active liverwort sesquiterpenes, trifarienols A and B, using phenylethylamine as a chiral auxiliary
    摘要:
    The imine of (rac)-2,3-dimethylcyclohexanone 10a with (S)-(-)-phenylethylamine was reacted with methyl acrylate to yield methyl (1'S,6'R)-3-(1',6'-dimethyl-2'-oxocyclohexyl)propanoate 4a in 26% (97% eel)after hydrolysis. When (2RS,3R)-2,3-dimethylcyclohexanone 10b, was used, the same product 4b was obtained in 59% yield (>99.5% ee) after hydrolysis. When (2RS,3R)-2,3-dimethylcyclohexanone 10b and (R)-(+)-phenylethylamine were used, the reaction underwent in only 5% yield, the products being 4c, 12, 13, 14, and 15. Thus, the reaction of 3b with methyl acrylate is a matched case, while that of 3c is a mismatched case. These phenomena are explained by the nonbonded interaction of methyl acrylate with chiral phenylethylamine and the methyl group at the 6'-position of the cyclohexanone ring in the transition state. The propanoate product 4b was successfully transformed into liverwort sesquiterpene (+)-trifarienol A 1 and (-)-trifarienol B 2 in 10 steps. We have developed an HPLC method to determine the ees of 2,2-disubstituted and 2,2,3-trisubstituted cyclohexanones using the corresponding pentafluorophenyl esters. (C) 1999 Elsevier Science Ltd.

    摘要:
    摘要 从属于Lejeuneaceae 的马来西亚地草Cheilolejeunea trifaria 中分离得到5 种新型双环非异戊二烯倍半萜烯醇,命名为trifarienols AE。它们的绝对结构是通过 NMR、CD 和 X 射线晶体学分析的组合确定的。Trifarienols 是苔藓植物中一个新的倍半萜烯系列。它们可能是通过在同一植物中共同出现的条纹烷型倍半萜类生物合成的。
