In the realm of biochemical research, chalcones have been efficiently explored as antimicrobial agents. The present study focuses on the synthesis of pyrimidine chalcones, i.e. (E)-1-(6'-hydroxy-1',3'-dimethyl-1',2',3',4'-tetrahydro-2',4'-dioxopyrimidin-5'-yl)-3-[-p-(1aEuro(3)-aryl-1H-1aEuro(3),2aEuro(3),3aEuro(3)-triazol-4aEuro(3)-yl) methoxy}phenyl]-prop-2-ene-1-ones (7a-7i) by the reaction of 4-triazolomethoxybenzaldehyde, i.e. 4-(1-aryl-1H-1,2,3-triazol-4-yl)methoxy}benzaldehyde (4a-4i) and 5-acetyl-1,3-dimethylbarbituric acid in (6) 50-80 % yields. The structures of these compounds were established on the basis of their FT-IR, H-1 NMR, C-13 NMR and mass spectral analysis. Compounds 7b-7i were screened for their in vitro antibacterial activity against Rhodococcus rhodochrous MTCC 265, a gram +ve bacteria and Escherichia coli, a gram -ve bacteria by the agar disc diffusion method.
