An efficient palladium/copper-catalyzed approach to the synthesis of highlysubstituted 3-formyl furans from the reactions of readily available α-bromoenaminones with terminal alkynes has been developed. This methodology was realized by the cascadereactions of Sonogashira coupling and the subsequent intramolecular cyclization.
