An asymmetric total synthesis of the novel and structurally complex epoxyquinol natural product (+)-panepophenanthrin has been accomplished, in which a biomimetic Diels–Alder dimerisation is a key step. The key monomeric precursor was assembled by an efficient Stille cross coupling of two readily available building blocks that upon standing underwent a diastereospecific dimerisation cascade in excellent
已经完成了新型和结构复杂的环氧喹啉天然产物(+)-泛对菲黄素的不对称全合成,其中仿生Diels-Alder二聚化是关键步骤。关键的单体前体通过两个容易获得的结构单元的高效Stille交叉偶联而组装,该模块在静置时以优异的产率进行了非对映异构的二聚级联反应。
