| titleOfInvention | Method for synthesizing heterocyclic compound by photoinduced metal-free catalyzed carbon arylation cascade reaction |
| abstract | The invention belongs to the technical field of organic synthesis, and discloses a method for synthesizing a heterocyclic compound by photoinduced metal-free catalyzed carbon arylation series reaction, which comprises the following steps: taking a compound shown in a formula III and a compound shown in a formula IV as substrates, stirring for 24-48 hours in an organic solvent under the action of a photosensitizer and an alkaline compound under the condition of room temperature and illumination, quenching reaction, extracting, washing, drying, concentrating and purifying to obtain the heterocyclic compound shown in the formula I or the formula II. The method disclosed by the invention has the advantages that the reaction is carried out under the illumination of room temperature, no metal catalysis is carried out, and compared with the traditional Ullmann-Hurtley coupling ring-closing reaction, the method does not need to add a catalyst, only needs to carry out the reaction under the room temperature condition, is low in energy consumption, greatly reduces the occurrence of side reactions, and is green and environment-friendly. |
