The DielsâAlder reaction of sulfoxide 2 with 1,3-dienes in CH2Cl2 afforded the corresponding CF3-containing mono- and polycycloadducts. In the case of the reaction of sulfoxide 2 and sulfonium salt 10 with cyclopentadiene, a mixture of four diastereomers was formed. The rotational potential energy surface (PES) of reagents 2, 10 was calculated and gave three minimum energy conformations with SO, Ph or the lone pair synperiplanar to the carbonâcarbon double bond.

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.
