Taking control of boron: A highly regio‐ and stereoselective copper‐catalyzed hydroboration of unsymmetrical internal alkynes has been developed. The regioselectivity was successfully controlled by the choice of catalytic species (copper hydride or boryl copper; see scheme).
控制硼:已经开发出高度区域选择性和立体选择性铜催化的不对称内部炔烃的硼氢化反应。通过选择催化物种(氢化铜或硼基铜;参见方案)成功控制了区域选择性。
