Synthesis and antimicrobial evaluation of ester-linked 1,4-disubstituted 1,2,3-triazoles with a furyl/thienyl moiety
文摘
Twenty ester-linked 1,4-disubstituted 1,2,3-triazoles having a furyl/thienyl moiety have been synthesized from heteroaryl prop-2-yn-1-yl carboxylate and aromatic azides via a Cu(I) catalyzed 1,3-dipolar cycloaddition. All the synthesized compounds were characterized by FTIR, \(^{1}\)H NMR, \(^{13}\)C NMR spectroscopy and HRMS. Synthesized triazoles were tested in vitro for antimicrobial evaluation against Gram-negative bacteria—Escherichia coli, Enterobacter aerogenes and Klebsiella pneumoniae; Gram-positive bacteria—Staphylococcus aureus and two fungal strains—Candida albicans and Aspergillus niger, reflecting moderate to good activity. The structure of compound 6f was also confirmed by X-ray crystallography (CCDC 1469326).
