Pd-catalyzed oxidative coupling of enamides and alkynes for synthesis of substituted pyrroles.

Abstract

A novel and efficient palladium(II)-catalyzed alkenyl C-H activation oxidative annulation of enamides with alkynes for the synthesis of substituted pyrroles has been developed. The reaction tolerates a wide range of functional groups and is a reliable method for the synthesis of triaryl-substituted pyrroles in high yields.
