Based on an unexpected product isolated during the LDA-mediated intramolecular cyclization of a benzyl alkynyl sulfones, a conceptually new cyclization method for the formation of 5,6-dihydro-1,4-oxathiin S,S-dioxides is demonstrated. The reaction affords
Separate deprotonation reactions converge mechanistically for a new cyclization of benzyl 1-Alkynyl sulfones

A heretofore unknown LDA-induced conversion of benzyl 1-alkynyl sulfones to 1H-2-benzothiopyran-S,S-dioxides is demonstrated. A benzyl carbanion, accessible by two means, is thought to cyclize by temporary disruption of aromaticity. Key intermediates are
