Diels–Alder reactions of β-trifluoroacetylvinylsulfones with 1,3-dienes in CH2Cl2 afforded corresponding mono- and polycycloadducts. A possibility of stereo- and regioselective cycloaddition was investigated. Elimination of sulfonyl group from cycloadducts leads to α,β-unsaturated trifluoromethylketones in good yields.
