The Synthesis of a variety of sulfines 8 derived from S-proline, utilizing the reaction of α-silyl carbanions with sulfur dioxide, is described.Reaction of the thus prepared sulfines 8 with 2,3-dimethyl-1,3-butadiene gave dihydrothiopyran S-oxides 9.During these cycloaddition reactions asymmetric inductions up to 40percent were observed.From one pure diastereomeric form of cycloadduct 9d an X-ray analysis was carried out in order to provide insight in the steric course of the cycloaddition reaction.
