Starting from the readily available parent flavonoids, the flavanone 6-prenylnaringenin, the isoflavone 6-prenylgenistein (wighteone, erythrinin B) and a protected derivative of the flavonol 6-prenylquercetin (gancaonin P) have been synthesized in short reaction sequences featuring the title processes as key steps.
从容易获得的母体类黄酮开始,以标题过程为特征的短反应序列,合成了黄烷酮6-异戊烯基柚皮素,异黄酮6-异戊二烯异黄酮(Wighteone,赤藓素B)和黄酮醇6-异戊二烯槲皮素(gancaonin P)的受保护衍生物。作为关键步骤。
