Tóm tắt
1,5-Disubstituted 1,2,3-triazoles are synthesized viametal-free multi-component reaction from primary amine, ketones and 4-nitrophenyl azide. The structure of three target compounds including:1-(4-methoxybenzyl)-5-(4-methylphenyl)-1H-1,2,3-triazole (1), 1-(4-methoxybenzyl)-5-(4-nitrophenyl)-1H-1,2,3-triazole (2) and 1-(4-methoxybenzyl)-5-phenyl-1H-1,2,3-triazole (3) is elucidated and identified by infrared spectroscopy, nuclear magnetic resonance spectroscopic analysis and high resolution mass spectrum. The formation of heterocyclic aromatic 1,2,3-triazole ring is approved by the appearance of singlet peak at 7.71 ppm in 1H NMR corresponding with triazolyl proton.
In addition, antibacterial and antifungal activities of products are also tested with three Gram-positive bacteria (B. subtilis, S. aureus and L. fermentum), three Gram-negative bacteria (P. aeruginosa, E.coli, S. enterica), and Candida albicans fungus.
