A rhodium-catalyzed [4 + 2] cycloaddition of ynamines and 2-(cyanomethyl)phenylboronates has been developed, leading to efficient and excellent regioselective synthesis of valuable indole-linked aromatic compounds in a concise and flexible approach. Interestingly, this strategy was successful in the construction of C···N axially chiral indoles with high enantiocontrol by the introduction of a new phosphoramidite
开发了铑催化的炔胺和2-(氰甲基)苯基硼酸酯的[4 + 2]环加成反应,以简洁灵活的方法高效、优异地区域选择性合成有价值的吲哚连接的芳香族化合物。有趣的是,该策略通过引入新的亚磷酰胺配体(Xie-Phos)成功构建了具有高对映体控制性的C·N轴向手性吲哚。
