A palladium-catalyzed three-component annulation of anilines, alkyne esters, and alkynes has been developed for the synthesis of polysubstituted pyrroles. The protocol demonstrates broad substrate scope and good functional group compatibility. The application experiments including gram-scale synthesis and derivatization of the product are performed to illustrate the synthetic potential. This method offers mild conditions and efficient access to polysubstituted pyrroles.
