We report here that polysubstituted cyclopent-2-enols can be constructed by the one-pot reaction of doubly activated cyclopropanes and α-EWG substituted acetonitriles under mild basic conditions via a domino-ring-opening-cyclization/deacylation/oxidation sequence. Moreover, the synthetic applications of these cyclopent-2-enols have been demonstrated in the late-stage derivatization into functionalized
我们在此报道,多取代的 cyclopent-2-enols 可以通过双活化
环丙烷和 α-EWG 取代的
乙腈在温和的碱性条件下通过多米诺-开环-环化/脱酰基/氧化序列的一锅反应构建。此外,这些 cyclopent-2-enols 的合成应用已在后期衍生为功能化 cyclopentapyrimidin-4-ones 和 2-hydroxy cyclopentanones 中得到很好的收率。
