We report the regioselective and enantioselective formal hydroamination of unsymmetrical internal alkenes catalyzed by a copper catalyst ligated by DTBM‐SEGPHOS. The regioselectivity of the reaction is controlled by the electronic effects of ether, ester, and sulfonamide groups in the homoallylic position. The observed selectivity underscores the influence of inductive effects of remote substituents
我们报告了由DTBM-SEGPHOS连接的铜催化剂催化的不对称内部烯烃的区域选择性和对映体选择性加氢胺化反应。反应的区域选择性由在均烯丙基位置的醚,酯和磺酰胺基团的电子效应控制。观察到的选择性强调了远程取代基的感应作用对在烃基上发生的催化过程的选择性的影响,该方法可直接获得各种具有高对映选择性的1,3-氨基醇衍生物。
