Supported Pd-catalyzed ring opening and chemoselective aminocarbonylative coupling of benzoxazoles with aryl iodides

Abstract

A tandem approach using polystyrene supported Pd catalyzed ring opening aminocarbonylative coupling of benzoxazoles with aryl iodides has been developed for the synthesis of N-(2-hydroxyphenyl)benzamides using solid oxalic acid as the CO source.
