Abstract

Abstract 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 ...
