Synthesis of some new 1,4-disubstituted 1,2,3-triazoles with ester functionality is reported employing Cu(I) catalyzed Huisgen [3+2] cycloaddition reaction of prop-2-yn-1-yl benzoates with 1,4-phenylenebis(methylene) bis(2-azidoacetate) and benzyl 2-azidoacetates. The synthesized compounds were well characterized through FTIR, 1H NMR, 13C NMR and HRMS. Further, the synthesized triazole derivatives were accessed for in vitro antimicrobial activity against one Gram-positive bacterial strain Staphylococcus aureus, three Gram-negative bacterial strains Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes and two fungi Candida albicans and Aspergillus niger. Few of the synthesized disubstituted 1,2,3-triazoles displayed moderate to good inhibitory activity against tested microbial strains.
报道了一种合成一些新型具有酯基功能的1,4-二取代-1,2,3-三氮唑的方法,该方法采用Cu(I)催化的Huisgen [3+2]环加成反应,以丙-2-炔-1-基苯甲酸酯与1,4-亚苯基双(亚甲基)双(2-叠氮乙酸酯)和苄基2-叠氮乙酸酯为原料。合成的化合物通过FTIR、1H NMR、13C NMR和HRMS进行了良好的表征。此外,合成的三氮唑衍生物在体外抗菌活性测试中,对一种革兰氏阳性菌金黄色葡萄球菌,三种革兰氏阴性菌大肠杆菌、肺炎克雷伯菌、产气肠杆菌和两种真菌白色念珠菌和黑曲霉进行了评估。少数合成的二取代1,2,3-三氮唑显示出对测试微生物菌株的中等到良好抑制活性。
