Palladium-Catalyzed Weak Chelation-Assisted Site-Selective C–H Arylation of N-Aryl Pyridones via 2-fold C–H Activation

Abstract

Palladium-catalyzed weak chelation-assisted oxidative cross-dehydrogenative coupling of arenes has been accomplished. The use of medicinally important pyridones as the intrinsic directing group, regioselectivity, 2-fold C−H activation, and late-stage modification of bioactive compounds are the important practical features.
