Studies of potential organo-fluorine antibacterial agents. Part 5: Synthesis and antibacterial activity of some new fluorine-containing indole-2,3-dione derivatives.

A series of new 1-dialkylaminoacetyl-5/6-fluoroindole-2,3-diones and 3-arylhydrazino-5/6-fluoro-1-morpholinomethylindol-2-ones have been synthesized; the former by the reaction of different secondary amines with N-chloro-acetyl-5/6-fluoroindole-2,3-diones and the latter, by the condensation of substituted phenylhydrazines with 5/6-fluoro-1-morpholinomethylindole-2,3-diones. All synthesized compounds have been characterized by their IR, 1H-NMR and elemental analysis. These compounds have been screened for their antibacterial activity against the Gram positive bacterium Staphylococcus albus and the Gram negative bacterium Escherichia coli.
