cascade O-sulfination and desulfurdioxidative N−N coupling (via stepwise retro-[2π+2σ] cycloaddition, supported by quantum chemistry calculations) from readily available N-arylhydroxylamines and N-sulfinylanilines under metal and oxidant free conditions.

Aromatic and aliphatic N-sulphinyl amines add smoothly to diphenyl and biphenylene ketene forming substituted 1,2-thiazetidinone-(3)-oxides-(1). An addition of ketene itself to N-sulphinyl cyclohexyl amine can be concluded from secondary products only.
Reaction of electron-deficient N-sulfinylanilines with chiral α-hydroxy acids: a new process for the synthesis of enantiomerically pure α-hydroxy amides
A practical procedure to prepare enantiomerically pure α-hydroxyamides from chiral α-hydroxy acids and electron-deficient anilines via N-sulfinylaniline derivatives has been developed.
