An enantioselective route to the key intermediate leading to (+)-vernolepin, an antitumor sesquiterpene, isolated from Vernonia hymenolepis, has been developed starting from the chiral building block having a bicyclo[3.2.1]octane framework accessible by either enzymatic or catalytic kinetic resolution.
从具有
双环[3.2.1]辛烷框架的手性结构单元开始,通过酶解或催化动力学解析,开发出了一种对映体选择性路线,可通过该路线获得从蕨麻(Vernonia hymenolepis)中分离出的抗肿瘤
倍半萜--(+)-vernolepin 的关键中间体。
