Most of the quinolone antibacterial research has been focused on the functionality at C-7 position where the nature of substituents is responsible for antibacterial spectrum, potency, bioavailability, and side effects of the quinolones. Then, a 7-amino-fluoroquinolone could be the starting point of a wide variety of potentially useful compounds like tetracyclic and tricyclic quinolones or secondary amines with side chain derivatives. This attracted our attention to synthesize a 7-azide-fluoroquinolone, which could be converted to amine performing a photochemical reaction using CuI as catalyst. FT-IR and H1 NMR spectra of the final product, ethyl 7-amino-1-ethyl-6,8-difluoroquinolone-3-carboxylate, suggests the formation of dimers, a feature already observed in norfloxacin.

A series of novel 8-fluoro Norfloxacin derivatives and the hybrids of its piperazinyl derivatives incorporated with 1,3,5-triazine and pyrimidine were synthesized. All the above compounds were evaluated for their antibacterial activity against Klebsiella pneumoniae, methicillin-resistant Staphylococcus aureus and methicillin & vancomycin-resistant S. aureus. Among all, compounds having Morpholine, N-methyl/phenyl/benzyl/pyrimidinyl piperazines and n-butylamine substitution at C-7 position, have shown increased potency in comparison to norfloxacin and ciprofloxacin.
