Utilizing a late‐stage enamine bromofunctionalization strategy, the twelve‐step total synthesis of (−)‐huperzine Q was accomplished. Furthermore, the first total syntheses of (+)‐lycopladines B and C are described. An unprecedented X‐ray crystal structure of an unusual epoxyamine intermediate is also reported, and the synthetic application of this intermediate in natural product synthesis is demonstrated
利用后期的烯胺溴官能化策略,完成了(-)-石杉碱Q的十二步全合成。此外,还介绍了(+)-番茄红素B和C的第一个总合成。还报道了一种罕见的环氧胺中间体的前所未有的X射线晶体结构,并证明了该中间体在天然产物合成中的合成应用。
