| titleOfInvention | A kind of synthetic method of β-bromotetrahydrofuran compounds |
| abstract | A method for synthesizing β-bromotetrahydrofuran compounds, the invention relates to a method for synthesizing β-bromotetrahydrofuran compounds. The invention aims to solve the problems of environmental pollution and low yield in the existing method for synthesizing β-bromotetrahydrofuran compounds. Synthesis method: Add enol compounds, bromination reagents, photoreaction catalysts and dry organic solvents into the reactor for reaction, and react at room temperature for 3h to 6h. After the reaction is completed, add distilled water to the reaction system, and then use ethyl acetate as The extraction agent is used for extraction, the organic phase is dried over anhydrous sodium sulfate and concentrated, and then separated and purified by silica gel column chromatography, thus completing the synthesis method of β-bromotetrahydrofuran compounds. Advantages: reaction at normal temperature and pressure, arbitrary feeding sequence, simple operation; visible light is used as the energy source for the reaction; high yield, safety and environmental protection, low cost, and belongs to the green chemical process. The invention is mainly used for the synthesis of a β-bromotetrahydrofuran compound. |
