Herein, we report the first enantioselective total synthesis of the highly complex hamigeran diterpenoid (−)-hamigeran F and its rearrangement product. The synthetic strategy features key steps of asymmetric hydrogenation, Horner–Wadsworth–Emmons olefination, and intramolecular Friedel–Crafts acylation to construct the [6,6,5]-tricyclic skeleton bearing three consecutive stereocenters, a sequence of
在这里,我们报告了高度复杂的 hamigeran 二萜 (-)-hamigeran F 及其重排产物的第一个对映选择性全合成。该合成策略的关键步骤包括不对称氢化、Horner-Wadsworth-Emmons 烯化和分子内 Friedel-Crafts 酰化以构建具有三个连续立体中心的 [6,6,5]-三环骨架,包括 Rosemund 还原、Wittig 的一系列步骤反应,二羟基化组装α-乙酰氧基酮基,分子内醛醇反应建立四环核心结构。
