A stereoselective formal synthesis of leucascandrolide A was accomplished through the tandem and organocatalytic oxa-Michael reactions, which were promoted by the gem-disubstituent effect, in conjunction with the dithiane coupling reaction.
通过串联和有机催化的氧杂-Michael 反应,以及二硫杂环戊烷偶联反应,协同双取代基效应,实现了左旋山德内酯 A 的立体选择性形式合成。
