| titleOfInvention | A method for preparing 2,3-disubstituted benzofuran derivatives |
| abstract | The invention discloses a method for preparing 2,3-disubstituted benzofuran derivatives, which comprises the following steps: (1) under the action of a rhodium catalyst, 1-sulfonyl-1,2,3-triazoles The compound reacts to obtain an imine intermediate; (2) under the action of palladium/carbon catalyst and 1atm H , the imine intermediate obtained in step (1) continues to react to obtain the described 2,3-disubstituted benzofuran derivative. The preparation method of the reaction raw materials in the method of the invention is simple, easy to store, simple and easy to operate, and less commercial rhodium catalysts are used, which can greatly reduce the cost. The method of the invention can be used to synthesize complex compounds containing 2,3-disubstituted benzofuran structure skeleton. |
