The stereoselective synthesis of complex targets requires the precise orchestration of chemical transformations that simultaneously establish the connectivity and spatial orientation of desired bonds. In this work, we describe a complementary paradigm for the synthesis of chiral molecules and their isomers, which tunes the three-dimensional structure of a molecule at a late stage. Key to the success
复杂目标的立体选择性合成需要精确协调化学转化,同时建立所需键的连通性和空间方向。在这项工作中,我们描述了手性分子及其异构体合成的互补范例,该范例在后期调整分子的三维结构。该策略成功的关键是开发一种由十钨酸聚阴离子和二硫化物助催化剂组成的温和且高度通用的光催化方法,该方法能够使先前构型固定的未活化的三级立体异构中心相互转化。
