Abstract Many 1,2,4-triazole derivatives have high biological activity. They are of interest for scientific and practical human activity as potential drugs and pesticides. In this work, we report a synthesis of a series of new 3-amino-1,2,4-triazole derivatives containing an alkylamide moiety. It was found that the amidoalkylation of 3-amino-1,2,4-triazole N-(1,2,2,2-tetrachloroethyl)carboxamides in the
摘要 许多1,2,4-三唑衍生物具有很高的生物活性。它们作为潜在的药物和杀虫剂对人类的科学和实践活动很感兴趣。在这项工作中,我们报告了一系列含有烷基酰胺部分的新型 3-氨基-1,2,4-三唑衍生物的合成。结果发现,3-氨基-1,2,4-三唑N- (1,2,2,2-四氯乙基)甲酰胺在三乙胺存在下选择性地在环内氮原子N -1 处发生酰胺烷基化,形成相应的N- (1-(5-氨基-1H- 1,2,4-三唑-1-基)-2,2,2-三氯乙基)甲酰胺。反应产物的分离产率为 79-85%,并通过1 H NMR 和13 C NMR 光谱进行表征。为了明确地确定所得化合物的结构,我们对N -(1-(5-amino-1 H -1,2,4-triazol-1-yl)-2,2,2 -三氯乙基)-3-甲基丁酰胺。
