Kudzuisoflavone-A was successfully synthesised via oxidative dimerisation of daidzein in the presence of cuprous chloride. Appropriately substituted isoflavones also undergo regioselective oxidative dimerisation when treated with thallium trifluoroacetate to give novel 6′,6′″-biisoflavones in good yield. A rationale for the regioselectivity is proposed.
Kudzuisoflavone-A是在氯化亚铜存在下通过大豆苷元的氧化二聚作用成功合成的。当用三氟乙酸th处理时,适当取代的异黄酮也进行区域选择性氧化二聚,从而以高收率得到新的6',6'''-二异黄酮。提出了区域选择性的基本原理。
