A novel and efficient synthesis of (−)-8-epi-swainsonine 2 is reported. Stereocontrolled diol formation from the bicyclic alkene 3 followed by a stereoselective vinylation of the aldehyde and ring closing metathesis gave the indolizidine ring system, which was converted into (−)-8-epi-swainsonine 2.
报道了(-)-8- epi- swainsonine 2的新颖和有效的合成。由双环烯烃3形成立体控制的二醇,然后对醛进行立体选择性乙烯基化,然后闭环易位,得到了吲哚并立定环系统,该系统被转化为(-)-8- epi- swainsonine 2。
