Thirty six novel heterocyclic derivatives of ethyl 2-(2-pyridylacetate) were efficiently synthesized. The new compounds involve the linkage of a 2-pyridyl ring with thiosemicarbazide (compounds 1–7), 1,2,4-triazole (compounds 1a–7a), 1,3,4-thiadiazole (compounds 1b–7b), and 1,3,4-oxadiazole (compounds 1f–7f) moieties. The last group of compounds 1e–7e involves the connection of a 2-pyridyl ring with
有效合成了 36 种新型 2-(2-吡啶基乙酸乙酯) 杂环衍生物。新化合物包括 2-吡啶环与氨基硫脲(化合物 1-7)、1,2,4-三唑(化合物 1a-7a)、1,3,4-噻二唑(化合物 1b-7b)和1,3,4-恶二唑(化合物 1f–7f)部分。最后一组化合物 1e-7e 涉及 2-吡啶环与 1,2,4-三唑和硫脲的连接。1H-NMR、13C-NMR和MS方法用于确认所得衍生物的结构。3、3b、7a和7f的分子结构通过X射线晶体学进一步证实。所有获得的化合物都在体外针对多种微生物进行了测试,包括革兰氏阳性球菌、革兰氏阴性杆菌和白色念珠菌。此外,
