The palladium-catalyzed coupling of 3- and 4-(trialkylstannyl)pyridines with 7-bromo or 7-chloro 1-substituted 1,4-dihydro-4-oxo-3-quinolinecarboxylates has provided access to the corresponding 1-substituted 1,4-dihydro-4-oxo-7-pyridinyl-3-quinolinecarboxylic acids.The antibacterial activity of these derivatives was studied with the finding that the optimal 1- and 7-position substituents for Gram positive activity are cyclopropyl and 4-(2,6-dimethylpyridinyl), respectively.We find that for the fluorine-substituted derivatives studied, the position of the fluorine on the quinolone nucleus or the number of fluorine atoms does not seem to be important for good Gram positive activity.For 1-cyclopropyl 7-(2,6-dimethyl-4-pyridinyl) derivatives, the 6-fluoro 4a, 8-fluoro 10d, 6,8-difluoro 10b, and 5,6,8-trifluoro 8, all provided equal antibacterial activity against Staphylococcus aureus ATCC 29213.There is also a correlation between the substitution on the 7-(4-pyridynyl) group and the Gram positive activity, particularly for S. aureus, clearly indicating that the 2,6-dimethylpyridil group is optimal.The MIC50 value for the most potent agents in this study against S. aureus ATCC 29213 is 0.008 mug/mL.By comparison, ciprofloxacin and aminopyrrolidine 28 gave values of 0.25 and 0.015 mug/mL, respectively, against this organism.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 96568-07-9, Ethyl 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate, introducing its new discovery.

The advantageous use of ionic liquids (ILs) as alternatives to common DMF as solvent in the Grohe cycloaracylation for the synthesis of pharmaceutically relevant quinolones is reported. ILs showed in many cases shorter reaction times and higher yields, complete conversions of the reactants and easy work-up procedures compared with DMF. Of the ILs screened, tributylmethylammonium methanesulfonate ([TBMA][MsO]) was selected as the most suitable for further studies. Interestingly, a wide substrate scope was observed and the IL was recycled by a green process. A further step forward in the use of [TBMA][MsO] for quinolone synthesis was the preparation by a one-pot/three-step procedure of the representative 3-carboxy-4-quinolone acid 16, which was obtained in high yield in a short time. The greener properties of ILs in comparison with DMF and their non-volatility appoint this method as a potentially efficient and alternative approach to the industrial production of quinolones.
