| titleOfInvention | Method for preparing 3, 4-dihydropyrimidine-2-one derivative by promoting high-efficiency catalysis of titanocene dichloride with ethanol |
| abstract | The invention discloses a method for preparing a 3, 4-dihydropyrimidine-2-one derivative by promoting high-efficiency catalysis of titanocene dichloride with ethanol, which takes aromatic aldehyde, beta-diketone and urea as raw materials, takes ethanol as a solvent and an accelerant, takes titanocene dichloride as a catalyst, and can prepare the 3, 4-dihydropyrimidine-2-one derivative with high efficiency and high yield under the synergistic promotion effect of ethanol. The catalyst used in the invention has the advantages of low dosage, low price, no toxicity, stability to air, mild reaction conditions, short time, simple operation and high atom economy, and the 3, 4-dihydropyrimidine-2-one derivative can be obtained by only carrying out simple column chromatography separation on the product after the reaction is finished, so that a new low-cost, green and efficient way is developed for the preparation of the 3, 4-dihydropyrimidine-2-one derivative, and the catalyst has a wide application prospect. |
