AB-ring core of Taxol was developed utilizing a new skeletal transformation protocol as a pivotal step. The acid-catalyzed rearrangement of the cyclopentenone–allene photoadduct gave a bridged seven-membered ketone, which was easily transformed, using the intramolecular Suzuki reaction and the oxidative cleavage of the vicinal diol, to the bicyclic diketone.
利用新的骨骼转化方案作为关键步骤,开发了构建紫杉醇AB环核心的新方法。酸催化的环戊烯酮-丙二烯光加合物的重排产生了桥连的七元酮,使用分子内Suzuki反应和邻二醇的氧化裂解,很容易将其转化为双环二酮。
