Abstract
The bromination of 3-alkyl- and 3-ethoxycarbonyl-2-oxo-4-hydroxyquinolones by molecular bromine gave 3-bromo-3-R-2,4-dioxoquinolones. Under analogues conditions, 1-R-2,4-dioxo-3H-quinolone-3-carboxylic acids form 1-R-3-bromo-2-oxo-4-hydroxyquinolones. The results of the study of the antimicrobial activity of the compounds synthesized are presented.
