Kudzuisoflavone-A was successfully synthesised via oxidativedimerisation of daidzein in the presence of cuprous chloride. Appropriately substituted isoflavones also undergo regioselective oxidativedimerisation when treated with thallium trifluoroacetate to give novel 6′,6′″-biisoflavones in good yield. A rationale for the regioselectivity is proposed.
Novel compounds based on phenyl-substituted naphtho[1,2-g]chrysene compounds (A) are described. The compounds are obtainable by dimerisation of 3-phenylchroman (isoflavonoid) ring systems (B). Methods of synthesis of the novel dimeric compounds, compositions containing same and use of the dimers as therapeutic agents are also described.
