synthesized by coupling 4-(4-methoxyphenyl)-6-(1H-1,2,4-triazol-1-yl)-1-(3-chlorophenyl)pyridin-2(1H)-one with substituted benzenediazonium chlorides in the form of two isomers, which were separated by column chromatography and characterized by 1H and 13C NMR. Following the green approach, solvents were avoided as much as possible. The reaction monitoring was carried out by gas chromatography as well
摘要 通过偶联4-(4-甲氧基苯基)-6-(1H-1,2,4-三唑-1-基)-1-(3-氯苯基)吡啶-2(1H)-酮合成了6-三唑基吡啶酮衍生物。具有两种异构体形式的取代苯重氮氯化物,通过柱色谱分离并通过 1H 和 13C NMR 表征。遵循绿色方法,尽可能避免使用溶剂。反应监测通过气相色谱以及薄层色谱进行。讨论了该方法的范围和限制。所有化合物的结构均已根据元素分析、红外和 NMR 光谱数据明确指定,并已评估其抗菌和抗结核活性。图形概要
