A new approach to steroid ring construction based on sequential cascade 6-endo-trig cyclisation/macrocyclisation/transannulation reactions and exemplified in the synthesis of the cis, anti, cis, anti, cis tetracycle 17 from 15, is presented.
本文介绍了一种基于顺序级联 6-endo-trig 环化/大环化/反式反应的甾环构建新方法,并以从 15 合成顺、反、顺、反、顺四环 17 为例证。
