Rosoxacin is not available in the United States. It was developed by Sanofi-Synthelabo (now part of sanofi-aventis). It is classified as first generation.[1] SynthesisThe synthesis of rosoxacin begins with a modified Hantzsch pyridine synthesis employing as component parts ammonium acetate, two equivalents of methyl propiolate, and one of 3-nitrobenzaldehyde. Oxidation of the resulting dihydropyridine (2) with nitric acid followed by saponification, decarboxylation, and reduction of the nitro group with iron and HCl acid gives aniline 3. This undergoes the classic sequence of Gould-Jacobs reaction with methoxymethylenemalonate ester to form the 4-hydroxyquinoline ring, and then alkylation with ethyl iodide and saponification of the ester to complete the synthesis of the antibacterial agent rosoxacin (4).
