Green synthesis and antibacterial evaluation of some new 1-aryl-3-(1-aryl-1H-[1,2,3]triazol-4-yl)-propenones

摘要

A new series of 1-aryl-3-(1-aryl-1H-[1,2,3]triazol-4-yl)propenones (6a-6j) was synthesized by condensation of substituted acetophenones (5a-5c) with substituted 1-aryl-1H-[1,2,3]triazole-4-carbaldehydes (4a-4d) in the presence of potassium hydroxide under conditions of grinding and microwave irradiation. All the newly synthesized compounds were characterized by the IR, NMR, and mass spectroscopic analyses and their antibacterial activity against gram-positive and gram-negative bacterial strains was evaluated. Among the compounds synthesized, better activity was exhibited by 6a, 6c, 6f, 6g, and 6i.
