Click Synthesis of Some mono/bis 1,2,3-Triazoles with Ester Linkage and their Microbicidal Activity

摘要

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-azidoaeetates. The synthesized compounds were well characterized through FTIR, ~1H NMR, ~(13)C 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.
