Starting from 4,4-dimethyl-2-cyclohexenone, an enantioselective synthesis of (-)-isopisiferin has been accomplished in 15 steps with an overall yield of 11.4 %. This work not only provides synthetic evidence for confirming the absolute configuration of natural isopisiferin itself, but also serves as an additional correlation origin to which many related icetexane-type diterpenes, particular for the
从 4,4-二甲基-2-环己烯酮开始,(-)-isopisiferin 的对映选择性合成分 15 个步骤完成,总产率为 11.4%。这项工作不仅为确认天然异匹西弗林本身的绝对构型提供了合成证据,而且还作为一个额外的相关起源,可以参考许多相关的冰泰克烷型二萜,特别是 pisiferin 家族。
