An efficient Cu(II)-vasicine catalytic system has been developed for intramolecular CN bond formation. In this way, regioselective 2-amination of o-haloanilides with aqueous ammonia in EtOH has been achieved. This strategy provides several advantages, such as good regioselectivity, high yields and functional group tolerance.
已经开发出用于分子内C N键形成的有效Cu(II)-水杨碱催化体系。以这种方式,已经实现了在EtOH中用氨水进行邻卤代苯胺的区域选择性2-胺化。该策略具有几个优点,例如良好的区域选择性,高产率和官能团耐受性。
