Synthesis of New N -Acyl-1,2,3-triazole Chalcones and Determination of Their Antibacterial Activity

Previously unknown N-acyl derivatives of 1,2,3-triazole chalcones have been prepared by the acylation of the potassium salts of 4-(3-oxo-3-phenylprop-1-en-1-yl)-5-phenyl-1,2,3-triazolides with carboxylic acid chlorides. The introduction of the N-acyl residue into the heterocyclic moiety of 1-aryl-3-(1H-1,2,3-triazol-4-yl)prop-2-en-1-ones has been shown to afford compounds with antibacterial activity.
