Natural inspiration: Based on the biosynthesis of squalene‐derived polyethers, a total synthesis of teurilene is described. The carbocation formation in the Nicholas reaction serves to control the initiation of a polyepoxide ring‐opening cascade. The three furan rings present in teurilene were obtained in excellent yield in one step. Boc=tert‐butoxycarbonyl, TMS=trimethylsilyl.
自然灵感:基于角鲨烯衍生的聚醚的生物合成,描述了丁二烯的全合成。尼古拉斯反应中的碳正离子形成可控制多环氧化物开环级联反应的起始。一步获得高产率的丁二烯中存在的三个呋喃环。Boc =叔丁氧羰基,TMS =三甲基甲硅烷基。
