(+)-Allomatrine (1) has been synthesized using an imino-aldol reaction and N-acyliminium cyclization as key steps. Strategically, use of the tert-butylsulfinimine derivative of (E)-4-(trimethylsilyl)but-2-enal enabled the staged formation of three C–C bonds, a C–N bond, and the four stereogenic centers within the target.
使用亚氨基-羟醛反应和N-酰基亚胺基环化作为关键步骤合成了(+)-异麦芽碱(1)。从策略上讲,使用(E)-4-(三甲基甲硅烷基)丁-2-烯醛的叔丁基亚磺胺衍生物可以在靶标内逐步形成三个C–C键,一个C–N键和四个立体中心。
