Abstract

A simple and convenient synthesis of some 3-arylimino-5-(N-4-methoxybenzylidenehydrazono)-1,2,4-dithiazolidines (IV a-e) has been achieved by oxidative debenzylation and cyclization of the corresponding 5-aryl-1-(4-methoxybenzylideneamino)-2-S-benzyliso-2,4-dithiobiurets (III a-e) which in turn were prepared by the condensation of certain potentially active S-benzyliso-4-methoxybenzylidenethiosemicarbazone (II) with appropriate aryl isothiocyanate. These dithiazolidines have been characterized by their synthesis through alternative routes (Scheme 1), elemental analyses and also by ir spectra.
