A copper-catalyzed synthesis of phenanthridine derivatives was developed starting from biaryl-2-carbonitriles and Grignard reagents. The present transformation is carried out by a sequence of nucleophilic addition of Grignard reagents to biaryl-2-carbonitriles to form N-H imines and their Cu-catalyzed C−N bond formation on the aromatic C−H bond, where molecular oxygen is a prerequisite to achieve the
从联芳基-2-腈和格氏试剂开始开发了铜催化的菲啶衍生物的合成。本发明的转化是通过将Grignard试剂亲核加成到联芳基-2-甲腈上以形成N -H亚胺并在芳香族C-H键上形成Cu催化的C-N键而进行的,分子氧为实现催化过程的前提条件。
