A novel cyclic sulfilimine, 2-methyl-2,4,1 -benzodithiazin-2-ium-1 -ide (4) was synthesized by deprotonation of the corresponding azasulfonium salt (3) with base. The compound 4 was oxidized with potassium permanganate to afford the sulfoximine 5, exclusively. On refluxing in several solvents, compo

Allylic phenyl and methyl sulfides bearing a strategically positioned electrophilic center have been shown to undergo concomitant C2,31-sigmatropic rearrangement and intramolecular N-alkylation upon oxidative conversion to allylic sulfilimines and treatment with aqueous base. This one-pot transforma
