摘要

A direct, efficient, and practical protocol to install a chiral Oxazoline unit onto aryl/heteroaryl rings via palladium-catalyzed C-H functionalization of 2-positions of oXazolines with a variety of halides using dppe as the ligand has been developed. Various chiral oxazdline ligands could be synthesized, even in a 10-g scale process. This protocol is a good supplement to traditional methods and for diverse synthesis of chiral oxazoline ligands.
