Synthesis, characterization and antimicrobial activities of some novel bis-chalcones
摘要:
A series of novel bis-chalcones 3a-n were synthesized in excellent yields by condensation reaction of 1,4-diacetylbenzene with various aldehydes in ethanol 96% and aqueous NaOH at room temperature. All compounds were characterized by IR, H-1 and C-13 NMR, UV spectroscopy and elemental analysis. The antimicrobial activities of synthesized compounds were also evaluated. The most of these compounds exhibited a good activity against Staphylococcus aureus, Escherichia coli and Candida albicans microorganisms. Some of them showed significant activities.
