Pd-Catalyzed Asymmetric Allylic C—H Functionalization

Comprehensive Summary Pd-catalyzed asymmetric allylic C—H functionalization has emerged as a powerful tool to access chiral,densely functionalized molecules from easily accessible alkenes,enabling the increase of the step-or atom-economy by minimizing functional group manipulations for preparing allylating reagents.Due to the inadequacy of stereoselection strategies,the asymmetric allylic C—H functionalization is still in the early stage.In this essay,we will describe our journey to identification of asymmetric catalytic systems,mechanism of allylic C—H activation,control of stereo-and regioselectivity,and applications in asymmetric synthesis.
