The preparation of new isoflavones

The synthesis of ten new isoflavones in good yield is described. The method, involving intermediate 2-hydroxybenzyl ketones, did not require protection of the hydroxyl groups of the starting polyphenols.

SYNTHETIC AND MODIFIED ISOFLAVONOIDS. XI. SYNTHESIS OF ANALOGUES OF MAXIMA ISOFLAVONE A AND XANTHOCERCIN

Analogues of maxima isoflavone A and of xanthocercin containing benzodioxolane, benzodioxane, and benzodioxepane fragments in rings A and B of isoflavone have been synthesized.The structures of the compounds obtained have been confirmed by analytical and spectral characteristics.

Synthesis of Petalostetin, an Isoflavone from Petalostemon candidum

Petalostetin (I), an isoflavone from Petalostemon candidum (Willd) Michx has now been synthesised by two unambiguous methods using 2'-hydroxy-3',4',5'-trimethoxy-3,4-methylenedioxychalkone (II) and 2,3,4-trihydroxy-3',4'-methylenedioxdesoxybenzoin (VI) as
