The stereoselective total synthesis of the piperidine alkaloids, (+)-coniine, (+)-pseudoconhydrine and (+)-sedamine has been achieved through a common intermediate generated from butane-1,4-diol. The synthetic sequence involves a Maruoka asymmetric allylation and ring-closing metathesis as the key steps.
哌啶生物碱,(+)-丝氨酸,(+)-伪conhydrine和(+)-sedamine的立体选择性全合成已通过由1,4-丁烷生成的常见中间体实现。合成序列涉及Maruoka不对称烯丙基化和开环易位作为关键步骤。
