4-amino-2-phenylindole-based compounds with potential antibacterial activity

Abstract

Primary condensation of 4-amino-2-phenylindole with ethyl acetoacetate and 4,4,4-trifluoroacetoacetate resulted in corresponding amides, which under acidic conditions were converted to pyrrolo[2,3-h]quinolones. Antibacterial activity of the amide obtained from aminoindole and ethyl 4,4,4-trifluoroacetylacetate was detected.
