Abstract: N-Glucosylated 1,2,4,5-dithiadiazines 5 have been synthesized by two different routes which involve the cyclo condensation of thiosemicarbazide and alkyl/arylimino chloromethane sulfenyl chloride. The first route involves the interaction of 4-tetra-O-acetyl-β-d-glucopyranosyl thiosemicarbazide and arylimino chloromethane sulfenyl chlorides while the other route involves the interaction of 4-aryl thiosemicarbazides and N-tetra-O-acetyl-β-d-glucopyranosylimino chloromethane sulfenyl chloride. This cyclo condensation results in sulfur-sulfur bond formation for which very few methods are available. The structures of the newly synthesized 1,2,4,5-dithiadiazines 5 have been confirmed on the basis of certain chemical transformations, IR, 1H and 13C NMR and mass spectral analyses.
