The invention discloses a preparation method of a phenanthridine derivative, which comprises: adding a catalyst, an oxidant, an acid, a 2-aminobiphenyl compound and an olefin compound into an organic solvent, and obtaining a phenanthridine derivative after completion of the reaction; The catalyst is a divalent palladium catalyst. The preparation method of the phenanthridine derivatives of the present invention avoids the use of highly toxic and highly corrosive reagents, is environmentally friendly, easy to operate, and has a high yield and easy post-treatment. In addition, the substrate obtained by the method can be designed. Strong, can be designed and synthesized according to the actual needs of the desired structure of the compound, strong practicability. |
