A new enantioselective total synthesis of epoxyquinols A and B possessing unique pentaketide dimeric structures and potent antiangeogenic activity was achieved by oxidative dimerization of a monomeric pentaketide precursor obtained by the Evans asymmetric aldol reaction and a series of operationally simple transformations.
通过由Evans不对称醛醇缩合反应获得的单体戊二醛前体的氧化二聚反应和一系列操作简单的转化,实现了具有独特的戊二烯二聚结构和有效的抗血管生成活性的环氧喹诺尔A和B的新对映选择性全合成。
