Enantiospecific first total synthesis of the angular triquinane sesquiterpene (6S,7R)-silphiperfolan-6-ol has been accomplished, starting from 2-(3-isopropenyl-2-methylene-1-methylcyclopent-1-yl)acetic acid (readily available from (R)-limonene) employing an efficient, regioselective intramolecular rhodium carbenoid insertion into the CH bond of a tertiary methyl group as the key step.
对映体特异性的角triquinane倍半萜烯(6第一全合成小号,7 - [R)-silphiperfolan -6-醇已经完成,从2-(3-异丙烯基-2-亚甲基-1-甲基环戊-1-基)乙酸(原料可以很容易地从(R)-柠檬烯中获得),其方法是将有效的区域选择性分子内铑类胡萝卜素插入叔甲基的CH键中,这是关键步骤。
