Popis: | Nitrogen-substituted 4-oxoquinoline-2-carboxylic acids have been prepared by the reaction of pentafluorobenzoylpyruvic acid with isopropyl-, cyclohexyl-, phenyl- and ethanol-amine. Ammonia and triethylamine, however, were found to react with pentafluorobenzoylpyruvic acid to form only the 2-carboxy-5,6,7-8-tetrafluorochromone; such behaviour has been found in the reactions of ethyl pentafluorobenzoylpyruvate with ammonia and cyclohexylamine. |
