Novel Quinolone Derivatives: Synthesis and Antioxidant Activity.

Novel quinolone derivatives have been designed and readily synthesized according to a simple protocol including O-alkylation and Claisen rearrangement processes. Structures of the synthesized compounds have been confirmed by IR, 1H and 13C NMR, and mass spectra. The new products have been tested for their antioxidant activity, and two of those demonstrate high antioxidant activity.
