A library of novel trans -ethyl 5-aroyl-4-aryl-2-((arylsulfonyl)methyl)-4,5-dihydrofuran-3- carboxylates were synthesized regio- and stereoselectively in good yields by a three-component domino reaction of ethyl-3-oxo-4-(arylsulfonyl)butanoates, aromatic aldehydes and N- phenacylpyridinium bromide in presence of triethylamine in acetonitrile under heating. This transformation generates C-O, C-C and
