EWG-containing thiophene-1,1-dioxides were found to be very active dienophiles in reactions with 1,3-dienes to afford corresponding cycloadducts in mild conditions. A chemo-, regio- and stereoselective cycloaddition was observed. Reaction resulted in formation of derivatives of tetrahydrobenzothiophene-1,1-dioxides in high yields.
