afforded 2-(1H-benzo[d][1,2,3]-triazol-1-yl)acetonitrile 2, which was reacted with sodium azide to give tetrazole derivative 3. Esterification of benzotriazole 1 with ethyl bromoacetate in the presence of anhydrous potassium carbonate afforded ester 4, which was treated with hydrazine hydrate to afford the corresponding hydrazide 5. Reaction of 3 with 2,3,4,6-tetra-O-acetyl-α-d-glucopyranosyl bromide afforded
一系列tetrazolomethylbenzo [的d ] [1,2,3]三唑衍生物(2 - 14)已被合成并评价为从-1H-苯并[抗微生物剂d ] [1,2,3]三唑(1)作为起始原料。苯并三唑1与氯乙腈的反应得到2-(1H-苯并[ d ] [1,2,3]-三唑-1-基)乙腈2,其与叠氮化钠反应得到四唑衍生物3。在无水碳酸钾存在下用溴乙酸乙酯将苯并三唑1酯化,得到酯4用水合肼处理,得到相应的酰肼5。的反应3与2,3,4,6-四ø -乙酰基α- d吡喃葡萄糖基溴化物,得到nitroglycoside衍生物6,其使用甲醇氨至脱保护的脱乙酰nitroglycoside 7。酰肼5与4,5,6,7-四氯邻苯二甲酸酐或1,2,4,5-苯四甲酸二酐在回流的冰醋酸中反应,分别得到相应的酰亚胺8和9。另外,使酰肼5与二硫化碳在乙醇中反应,得到钾盐。10,与水合肼反应得到氨基三唑衍生物11。使后者化合物与
