Substitution of tosyl group on hydroxy acetophenones or hydroxy benzaldehyde and their subsequent condensation yielded several tosyloxy substituted chalcones which were derivatized to obtain the corresponding pyrimidinethione derivatives. The synthesized compounds were characterized by spectroscopic techniques like FT-IR, 1H NMR, 13C NMR, and mass spectrometry. These compounds were subjected to initial screening for their bioactivity using zone of inhibition method and were found to be moderately active against the tested microorganisms, viz. Mycobacterium smegmatis, Staphylococcus aureus, Escherichia coli, and Candida albicans.
Key words: Chalcones, Pyrimidine derivatives, Antimicrobial property, Spectral characterization
