Novel naphthyridine-, and quinolinecarboxylic acids as antibacterial agents are described as well as methods for their manufacture, formulation, and use in treating bacterial infections including the description of certain novel intermediates used in the manufacture of the antibacterial agents.
ortho-Disubstituted<i>F</i>-Benzenes. V. Intramolecular Heteroatom-facilitated ortho-Substitution of<i>F</i>-Benzene Derivatives with Oxazolinyl and Oxazinyl Groups
oxazolinyl substituents on an F-benzene ring facilitated the substitution of fluorine ortho to the heterocyclic functional groups by carbon and nitrogen nucleophiles. Alkylmagnesium halides and alkyllithium compounds were employed as the carbon nucleophile, and lithium N-methylanilide and N-methylanilinomagnesium halide as the nitrogen nucleophile. The selective ortho-substitution was accomplished by the
