| titleOfInvention | Preparation method of fluoroalkyl-substituted benzofuran derivative or indole derivative |
| abstract | The invention belongs to the technical field of pharmaceutical chemical synthesis, and discloses a preparation method of a fluoroalkyl-substituted benzofuran derivative or indole derivative, which comprises the following steps: taking a 2-allyl phenol compound or a 2-allyl-aniline compound as a raw material, adding alkali, a fluoroalkyl reagent, a solvent and a photocatalyst, stirring the obtained solution under the atmosphere of illumination and nitrogen for reaction, extracting the reaction solution after the reaction is finished, removing the solvent under reduced pressure to obtain a crude product, and purifying to obtain the fluoroalkyl-substituted benzofuran derivative or indole derivative. The method for synthesizing fluoroalkyl-substituted benzofuran derivatives and indole derivatives efficiently through photocatalysis has the advantages of simplicity, easiness, mild reaction conditions, wide adaptability to substrates, high product yield and good industrial application prospect. |
