Chitosan supported Cu nano-particles have been synthesized, and utilized for the synthesis of 3-nitro-4-quinolones from 3-carboxy-4-quinolones via ipso nitration. The synthesized 3-nitro derivatives of 4-quinolones were successfully converted into their 3-tetrazolyl bioisosteres which showed increased antibacterial activity as compared to the standard ciprofloxacin.
