摘要：
N-Glycosyl-2-(1,4,5,6-tetrahydropyridazin-6-one-3-carbonyl)-hydrazinecarbothioamides (3a-3f) and N-glycosyl-2-(1,6-dihydropyridazin-6-one-3-carbonyl)-hydrazinecarbothioamides (5a-5f) were prepared by the reaction of glycosyl isothiocyanates with the compounds 1,4,5,6-tetrahydro-3-hydrozinecarbonyl-6-pyridazinone (1) and 1,6-dihydro-3-hydrozinecarbonyl-6-pyridazinone (2). The terminal heterocyclic compounds 1,3,4-thiadiazoles derivatives were obtained from cyclization of compounds 3a-3f and 5a-5f by phosphoric acid. The structures of all the compounds were confirmed by elemental analysis and IR, H-1 NMR, LC-MS (ESI) spectral data.
