tert-butoxide-mediated condensation reactioninvolving a vinyl sulfoxide intermediate. Products are obtained from N- or O-benzyl benzaldehydes using dimethyl sulfoxide as a carbon source. The methodology features a wide functional group tolerance and transition metal-free environment. Preliminary mechanistic studies suggest that the reactioninvolves a tandem aldol reaction/Michaeladdition/dehydrosulfenylation/isomerization
