Eight neoflavones were synthesized for examination of their spectral properties.In the mass spectra, 2'-oxygenated neoflavones showed characteristic fragments owing to dehydrxylation or demethoxylation.Other spectral data ultraviolet, proton and carbon-13 nuclear magnetic resonance, however, showed no specific features that could be used to characterize the structures.Keywords--neoflavone synthesis; 4-arylcoumarin; 2'-oxygenated neoflavone; mass spectrum
