Synthesis of New Naturally Occuring 4-Phenyl-2H-1-benzopyran-2-ones

5,7-Dimethoxy-4-(4-hydroxyphenyl)-2H-1-benzopyran-2-one and 5,7-dimethoxy-4-(4-methoxyphenyl)-2H-1-benzopyran-2-one, two new neoflavonoids occuring in Courtarea hexandra have been synthesized via Pechmann condensation.Attempts made to synthesize another 4-arylcoumarin, 5-hydroxy-7-methoxy-4-(2,5-dihydroxyphenyl)-2H-1-benzopyran-2-one, constituent of the same plant, led to the formation of the hitherto unknown 2-ethoxy-6-hydroxy-4H-1-benzopyran-4-one.

Flavonoids Syntheses. VI. Synthesis and Spectral Properties of 4-Arylcoumarins (Neoflavones)

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
