aza-Prins reaction is a widely employed and highly efficient method for the preparation of saturated nitrogen-containing heterocycles. Its major drawback has always been a lack of diastereoselectivity and the formation of racemic products. Herein, we address these problems and report, for the first time, the synthesis of both diastereomerically and enantiopure multiply substituted piperidines via the aza-Prins
氮杂-普林斯反应是制备饱和含氮杂环的一种广泛采用的高效方法。其主要缺点一直是缺乏非对映选择性和外消旋产物的形成。本文中,我们解决了这些问题,并首次报告了通过aza-Prins反应合成非对映异构和对映纯的多取代
哌啶的方法。该方法广泛适用于
天然产物的合成,并在此以对映纯的
胡椒酸衍
生物的合成为例。
