Synthetic method and catalyst of dihydropyrimidinone compounds |
| abstract |
The invention discloses a method for synthesizing dihydropyrimidinone compounds and a catalyst, and mainly relates to the technical field of organic synthesis. The method for synthesizing dihydropyrimidone compounds is synthesized by using ethyl acetoacetate, aromatic aldehyde and urea as raw materials, using silica gel supported organic acid as catalyst and ethanol as solvent, and synthesizing in one pot. The beneficial effects of the invention are as follows: it provides a method for synthesizing dihydropyrimidinone compounds with mild reaction conditions, simple operation and environmental protection. |
