In search for new antioxidant agents derived from 6-azauracil, the spiro-5-(flurin-9’-yl)-6-azauracil 3 and their N , N -disubstituted-6-azauracils 4 - 17 have been synthesized using various methods and reaction conditions. Structure of the new synthesized compounds was deduced from elemental analysis and spectral measurements, for example IR, 1H/13C NMR and mass spectroscopy. The antioxidant evaluation of the new targets showed that the activity increases in the order of 8 > 10 > 6 > 7 > 9 in comparison with 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and ascorbic acid as standards.
