Synthesis and Antimicrobial Activity of 2‐(4‐(Hydroxyalkyl)‐1H‐1,2,3‐triazol‐1‐yl)‐N‐substituted propanamides

Abstract

A series of 21 2‐(4‐(hydroxyalkyl)‐1H‐1,2,3‐triazol‐1‐yl)‐N‐substituted propanamides (1,4‐disubstituted 1,2,3‐triazoles having amide linkage and hydroxyl group) have been synthesized from click reaction between terminal alkyne and 2‐azido‐N‐substituted propanamide (generated in situ from reaction of 2‐bromo‐N‐substituted propanamide and sodium azide) and characterized by FTIR, 1H NMR, 13C NMR spectroscopy, and HRMS. All the newly synthesized triazoles were tested in vitro for antimicrobial activity against four bacterial cultures – Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, and Staphylococcus aureus – and two fungal cultures – Candida albicans and Aspergillus niger. The synthesized 1,4‐disubstituted 1,2,3‐triazoles displayed moderate to good antimicrobial potential against the tested strains.
