The Diels-Alderreaction of an optically active vinyl sulphoxide containing a second electron withdrawing group with cyclopentadiene gave separable diastereomers. The effect of Lewis acid catalysis on the reaction was studied. Reaction of an acetylenic anion with menthyl p-toluene sulphinate gave an anomalous product.
