Synthesis and Antibacterial Activity of 3-Phenyl-5,7-Dibromo-6-Methyl-4-Substituted Styrylcoumarin

摘要

Some new 4-styrylcoumarin derivatives have been prepared by condensation of 2'-phenylacetyloxy-5'-methyl4',6'-dibromochalcone with potassium hydroxide in presence of pyridine, The structure of the product has been characterised by elemental analysis and IR studies. The products have been screened for antibacterial activity against Staphylococcus aureus and Escherichia coli.
