The bicyclo[4.3.0]nonane core of the austrodorane family of sesquiterpenoids has been synthesized via a novel transannular Prins cyclization. This strategy formed the fused 5,6-ring system and installed the required quaternary stereocentre at the ring fusion in a single step.
倍半萜类奥杜拉烷家族的双环[4.3.0]壬烷核心是通过新颖的跨环普林斯环化合成的。该策略形成了稠合的5,6-环系统,并在单个步骤中在环融合处安装了所需的四元立体中心。
