An efficient Cu-catalyzed intramolecular hydroarylation reaction of alkynes has been developed. The reaction is accomplished under mild conditions and shows good tolerance to both electron-rich and electron-deficient aryl nucleophiles. A series of aryl, heteroaryl, alkyl, and even N-group attached alkynes are all suitable substrates for the intramolecular hydroarylation.
我们开发了一种高效的铜催化炔烃分子内加氢反应。该反应在温和的条件下完成,对富电子和缺电子的芳基亲核物都有很好的耐受性。一系列芳基、杂芳基、烷基甚至 N 基团连接的炔烃都是分子内加氢反应的合适底物。
