7,8-Methylenedioxy-3',4'-dimethoxyisoflavone (I), a new isoflavone isolated from the aerial parts and roots of Tephrosia maxima has been synthesized by oxidative rearrangement of 2'-hydroxy-3',4'-methylenedioxy-3,4-dimethoxychalcone (IV) with thallium(III) nitrate (TTN) in trimethyl orthoformate (TMOF), followed by acid-catalysed cyclization.It has also been synthesized from 2,3,4-trihydroxy-3',4'-dimethoxydeoxybenzoin (V).

6,7-Methylenedioxy-3',4'-dimethoxyisoflavone (I) has been synthesized from 2',4',5'-tribenzyloxy-3,4-dimethoxy-chalkone (III).The epoxide (IV) of III is converted into the isoflavone (VI) trough the α-formyldesoxybenzoin (V).Methylenation of VI gives I.
