在KOH溶液中, 芳甲酰肼(2)与CS2生成钾盐3; 然后3在水合肼作用下经过环化、取代、肼解得3-巯基-4-氨 基-5-苯基-4H-1,2,4-三唑-乙酸酰肼(6), 6再与CS2回流成环生成化合物5-(4-氨基-5-苯基-4H-1,2,4-三唑-3-硫烷基)-1,3,4-噁二唑-2-硫醇(7), 最后7与取代苄基氯反应得目标化合物A1A6, 与芳基甲醛反应得终产物B1B15. 目标化合物的结构均经1H NMR, 13C NMR, IR, MS或HRMS确证结构.

关键词: 1,2,4-三唑, 1,3,4-噁二唑, 硫醚

Compound 3 was prepared by reaction of benzohydrazide (2) with CS2 in the presence of KOH as solvent. This compound converted to (4-amino-5-phenyl-4H-1,2,4-triazol-3-ylsulfanyl)-acetic acid hydrazide (6) by the reactions of cyclization, substitution and hydrazinolysis in the presence of hydrazine hydrate. Then 5-(4-amino-5-phenyl-4H-1,2,4-triazol- 3-ylsulfanylmethyl)-1,3,4-oxadiazole-2-thiol (7) were obtained by a refluence of compound 6 with CS2. This intermediate reacted with several substituted-benzyl chloride to afford a series of new derivatives A1A6; in the meantime, reacted with several substituted-benzaldehyde to afford a series of new derivatives B1B15. The structures of new products were characterized by means of 1H NMR, 13C NMR, IR, MS or HRMS techniques.
