AbstractN‐Glycosyl‐2‐(1,4,5,6‐tetrahydropyridazin‐6‐one‐3‐carbonyl)‐hydrazinecarbothioamides 3a‐3g and N‐glycosyl‐2‐(1,6‐dihydropyridazin‐6‐one‐3‐carbonyl)‐hydrazinecarbothioamides 5a‐5g 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‐oxadiazole derivatives were obtained from cyclization of compounds (3a‐3g) and (5a‐5g) by mercuric acetate. Their structures were confirmed by IR, 1H NMR, MS and elemental analyses.
