| titleOfInvention | Method for selectively synthesizing dihydrophenanthridine or phenanthridine compounds |
| abstract | The invention discloses a method for selectively synthesizing a dihydrophenanthridine compound 3 or a phenanthridine compound 4, belonging to the technical field of organic synthesis. Taking an o-aryl aniline compound 1 and an alkynoate compound 2 as raw materials, and carrying out a heating reaction in an organic solvent in the presence of a ruthenium catalyst, an additive and an acid to obtain a dihydrophenanthridine compound 3 or a phenanthridine compound 4; the invention has the following advantages: 1) the synthesis process is simple, and the dihydrophenanthridine or phenanthridine compound can be synthesized with high selectivity by starting from an o-aryl aniline compound and an alkynoate compound and changing the reaction temperature under the catalysis of a ruthenium catalyst; 2) the raw materials are cheap and easy to obtain, the reaction condition is mild, the operation is simple and convenient, and the application range of the substrate is wide. |
