Twenty ester-linked 1,4-disubstituted 1,2,3-triazoles having a furyl/thienyl moiety have been synthesized from heteroaryl prop-2-yn-1-yl carboxylate and aromatic azides via a Cu(I) catalyzed 1,3-dipolar cycloaddition. All the synthesized compounds were characterized by FTIR, [Formula: see text]H NMR, [Formula: see text]C NMR spectroscopy and HRMS. Synthesized triazoles were tested in vitro for antimicrobial evaluation against Gram-negative bacteria-Escherichia coli, Enterobacter aerogenes and Klebsiella pneumoniae; Gram-positive bacteria-Staphylococcus aureus and two fungal strains-Candida albicans and Aspergillus niger, reflecting moderate to good activity. The structure of compound 6f was also confirmed by X-ray crystallography (CCDC 1469326).
通过铜(I)催化的1,3 - 偶极环加成反应,由杂芳基丙 - 2 - 炔 - 1 - 基羧酸盐和芳香族叠氮化物合成了20种具有呋喃基/噻吩基部分的酯键连接的1,4 - 二取代1,2,3 - 三唑。所有合成的化合物均通过傅里叶变换红外光谱(FTIR)、氢核磁共振光谱(¹H NMR)、碳核磁共振光谱(¹³C NMR)和高分辨质谱(HRMS)进行了表征。对合成的三唑进行了体外抗菌活性测试,针对革兰氏阴性菌——大肠杆菌、产气肠杆菌和肺炎克雷伯菌;革兰氏阳性菌——金黄色葡萄球菌以及两种真菌菌株——白色念珠菌和黑曲霉,结果显示出中等至良好的活性。化合物6f的结构也通过X射线晶体学得到了证实(剑桥晶体数据中心编号CCDC 1469326)。
