Synthesis of 2‐Arylbenzoxazoles by Copper‐Catalyzed Intramolecular Oxidative CO Coupling of Benzanilides

Abstract

No need for additives: A wide variety of functionalized 2-arylbenzoxazoles can be prepared with high functional-group tolerance and regioselectivity by a copper-catalyzed intramolecular oxidative CO coupling of benzanilides. The catalytic cycle is completed by the regeneration of the copper catalyst using molecular oxygen as a terminal oxidant without the need for additives.
