NMR Spectroscopic Study of Quinolone Carboxylic Acid Derivatives

Abstract

Authors synthesized common intermediates which are applicable for potential antibiotics. Their complete 13C and 1H NMR chemical shift data as well as carbon- and proton-fluorine coupling constants are reported. The knowledge of proton- and carbon-fluorine coupling constants may help one assign the NMR data of the fluorinated quinolone derivatives. These results agree with the data published previously.
