An approach to 2-substituted isoflavonoids is reported based on the 1,2-shift of the aryl group in the catechin skeleton followed by the in situ alkylation. Synthesis of (-)-equol, a natural isoflavan with estrogenic activities, was achieved.
据报道,基于儿茶素骨架中芳基的1,2-转移,然后进行原位烷基化,可以实现2-取代异黄酮的制备。合成了具有雌激素活性的天然异黄酮(-)-雌马酚。
