Abstract:

The synthesis of naturally occurring 7,8-methylenedioxy-4'-methoxyisoflavone and 7,8-methylenedioxy-4'-methoxyflavone from 2'-hydroxy-3',4'-methylenedioxy-4-methoxychalcone via the intermediacy of 7,8-methylenedioxy-4'-methoxyflavanone using thallium(III) acetate and catalytic amount of perchloric acid is reported. The products flavanone and the flavone are new flavonoids characterised by spectral analysis.
