Synthesis and Antimicrobial Evaluation of (1-(2-(Benzyloxy)-2-oxoethyl)-1H-1,2,3-triazol-4-yl)methyl Benzoate Analogues

A convenient one pot synthesis of 20 (1-(2-(benzyloxy)-2-oxoethyl)-1H-1,2,3-triazol-4-yl)methyl benzoate analogues (5a-5t) with ester functionality was carried out via Cu(I) catalyzed click reaction between prop-2-yn-1-yl benzoates and benzyl 2-azidoacetates. The structure of synthesized triazoles were explicated by various spectral techniques like FT-IR, H-1 NMR, C-13 NMR, and high-resolution mass spectrometry and evaluated for in vitro antimicrobial potential against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes, Candida albicans, and Aspergillus niger. Most of synthesized triazole derivatives exhibited average to excellent activity against tested microbial strains.
