An enantioselective copper‐catalyzed intramolecular borylacylation is reported. The reaction proceeds through an initial enantioselective borylcupration of the styrene, followed by a nucleophilic attack on the tethered carbamoyl chloride. The products, chiral borylated 3,3‐disubstituted oxindoles, were generated in excellent yields and enantioselectivities. The versatile carbon–boron bond provides
据报道对映选择性铜催化的分子内硼烷基化。该反应通过苯乙烯的初始对映选择性硼基富集进行,然后对系留的氨基甲酰氯进行亲核攻击。手性硼酸化的3,3-二取代的羟吲哚类产品以优异的收率和对映选择性产生。通用的碳-硼键为广泛的多样化提供了平台。
