Eight neoflavones were synthesized for examination of their spectral properties. In the mass spectra, 2'-oxygenated neoflavones showed characteristic fragments owing to dehydroxylation 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.
