Synthesis of substituted oxazoles via Pd-catalyzed tandem oxidative cyclization

Abstract

A novel method for the synthesis of multisubstituted oxazoles by palladium-catalyzed oxidative cyclization of N-acyl enamides has been developed. The reaction employs readily available iodobenzenes and enamides as the starting materials under mild reaction conditions and provides a reliable way to achieve versatile substituted oxazole derivatives.
