The catalytic intermolecular diamination of unactivated alkenes with electron-rich amino sources is a challenge. Herein, by employing a directing-group strategy, a copper-catalyzed diamination of unactivated alkenes was realized. Symmetrical diamines were efficiently produced in a highly diastereoselective manner with readily available dialkylamines as amino sources, while a one-pot and two-step operation was necessary to produce the unsymmetrical diamines. These reactions were proposed to proceed through aziridinium intermediates.
富电子胺源催化的非活化烯烃的分子间双氨化反应是一个挑战。在此，通过采用导向基团策略，实现了铜催化的非活化烯烃的双氨化反应。以易得的二烷基胺作为胺源，以高非对映选择性的方式有效地合成了对称二胺，而合成不对称二胺则需要一锅两步的操作。这些反应被认为是通过氮丙啶中间体进行的。
