Abstract The domino reactions of (Z,Z)-2,2′-thiobis(1,3-diarylprop-2-en-1-ones) with acetylacetone and ethyl acetoacetate in the presence of sodium ethoxide afforded the corresponding 4,5-dihydrofurans stereoselectively in moderate yields presumably via a Michael addition–enolization–displacement sequence.
