A Novel Process for the Key Intermediate of Fluoroquinolones.

This article discusses the synthesis of key intermediates for the production of fluoroquinolones, a group of antibiotics. The article compares two existing synthetic routes for these intermediates and highlights their limitations. The authors then propose a new synthetic route that utilizes a cheaper starting material and achieves a higher overall yield. The new route is described in detail, including the experimental procedures and results. The authors acknowledge the financial support they received for this research. [Extracted from the article]
