Abstract
A novel series of compounds containing coumarinyl moiety derivatives from 2-(2-oxo-4-phenyl- 2H-chromen-7-yloxy)-acetohydrazide (2) were synthesized. The formed compounds have been evaluated by correct elemental analysis and spectral data (IR, MS, 1H-NMR and 13C-NMR). The antioxidant evaluation of some selected compounds indicated that tosyl hydrazide derivative 7 revealed promising antioxidant activity.
