Naphthyridones

1,8-Naphthyridine is an organic compound with the formula C8H6N2. It is the most well-studied of the six isomeric naphthyridines, a subset of diazanaphthalenes with nitrogen in the separate rings. Enoxacin, nalidixic acid, and trovafloxacin are 1,8-naphthyridine derivatives with antibacterial properties related to the fluoroquinolones. Witryna4 wrz 2003 · Naphthyridones bearing the appropriate substituents could be constructed from aniline and acetonedicarboxylate (ADC) or by the recently discovered tandem Heck—lactamization process from acrylamide and trihalopyridine.
