Synthesis of novel five-membered endocyclic sulfoximines - 1-aryl-3-(arylimino)-3,5-dihydro-1,4,2-dithiazole 1-oxides

A novel kind of five-membered endocyclic sulfoximines, 1-aryl-3-(arylimino)-3,5-dihydro-1,4,2- dithiazole 1-oxides, were synthesized through addition/cyclization of chloromethyl aryl sulfoximines with aryl isothiocyanates under mild reaction conditions in moderate to good yields.
