Synthesis, Characterization And Antimicrobial Analysis Of Various Substituted 2-(3-(3-Bromothiophen-2-Yl)-1-Phenyl-1h-Pyrazol-4-Yl)-4h-Chromen-4-One

We have developed a protocol for the synthesis of some novel chromones from various chalcones by using I-2 in DMSO. All the products were characterized by IR, NMR and Mass spectral data. In addition to this newly synthesized compounds have been screened for their antimicrobial activity against Gram +ve and Gram -ve microorganisms. Some of the compounds show moderate antimicrobial activity.
