Abstract
Synthesis of some amide-ester linked 1,4-disubstituted 1,2,3-triazoles was carried out by employing copper(I)-catalyzed 1,3-dipolar cycloaddition of 2-azido-N-substituted acetamides and benzoic acid prop-2-ynyl esters. All the synthesized 28 1,4-disubstituted 1,2,3-triazoles are new. The synthesized triazoles were characterized by IR, 1H NMR, 13C NMR, HRMS and evaluated for their antimicrobial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans, and Aspergillus niger. Compounds displaying potent antimicrobial activity against each of these microorganisms were found. Quantitative structure activity relationship studies for the synthesized compounds were also carried out to check the effect of various substituents in parent compound on antimicrobial activity.
