Palladium-Catalyzed Oxidative Three-Component Coupling of Anthranilamides with Isocyanides and Arylboronic Acids: Access to 2,3-Disubstituted Quinazolinones

Abstract

A novel palladium-catalyzed oxidative three-component coupling of easily accessible N-substituted anthranilamides with isocyanides and arylboronic acids is achieved. This protocol offers an alternative approach toward 2,3-disubstituted quinazolinones with a wide substrate scope and good functional group tolerance.
