Convenient and highly efficient syntheses of tetrasubstitutedfurans with flexible substituent patterns fromsimple and readily available starting materials have been developed. Under very mild conditions, with the mediation of stoichiometric nBu3P, simpleterminalactivatedolefins and acyl chlorides or anhydrides smoothly furnish tetrasubstitutedfurans in modest to excellent yields. This synthetic
