Aromatic acid underwent esterification, hydrazinolysis, cyclization and then introduction of hydrazino group again to give 2-hydrazino-5-aryl-1,3,4-oxadiazoles (2). Aryl thiourea underwent cyclization and hydrazinolysis to give 2-hydrazino-4/6-substituted benzothiazoles (3). After nucleophilic addition of glycosyl isothiocyanate (1) to 2, 3 and N-substituted thiosemicarbazides (4), aseries of novel N-glycosyl-2-substituted-thiosemicarbazide and N-glycosyl-N'-substituted-bithiourea derivatives have been synthesized. The structures of the compounds were established on the basis of IR, 1H NMRand MS spectral data. The absorption around 900 cm－1 in IR spectra and coulpling constant JCl—H=9～10 Hz in 1H NMR spectra confirmed that all compounds have β-configuration.

Key words: glycosyl isothiocyanate, thiosemicarbazide, bithiourea, synthesis
