The stereochemistry of the epcxidation of the title compound with t-BuOOH catalysed by VO(acac)2 is subject to exclusive homoallylic control. Secondary allylic alcohols in the side chain regain their normal controlling influence over diastereoselection only when the homoallylic group is blocked.
VO(acac)2催化的带有t-BuOOH的标题化合物的环氧固定化的立体
化学必须进行均一的均聚物控制。仅当均烯丙基被封端时,侧链中的仲烯丙基醇才重新获得非对映选择性的正常控制影响。
