The asymmetric total synthesis of vinorine, a polycyclic and cage-like alkaloid, has been realized in a flexible approach. Key features of the current synthesis include an aza-Achmatowicz rearrangement/Mannich-type cyclization to install the highly functional 9-azabicyclo-[3.3.1]nonane scaffold, a high yield Fischer indole annulation to synthesize the common intermediate for sarpagine-ajamaline type alkaloids, and an Ireland-Claisen rearrangement to construct the C15-C20 bond.
不对称全合成多环笼状生物碱 vinorine 的方法已经实现。目前合成的关键特点包括氮杂-Achmatowicz 重排/Mannich 型环化反应来构建高度功能化的 9-氮杂双环[3.3.1]壬烷骨架，高产率 Fischer 吲哚环合反应来合成 sarpagine-ajamaline 型生物碱的共同中间体，以及 Ireland-Claisen 重排反应来构建 C15-C20 键。
