The invention discloses a method for synthesizing 3,4,5-substituted pyrazole compounds. In a reaction solvent, a lipid compound of diazoacetic acid and a carbonyl compound containing α-H are used as raw materials, and amine compounds are catalyzed. Next, the reaction yields 3,4,5-substituted pyrazoles. The invention has cheap and easy-to-obtain raw materials, mild reaction conditions, simple and convenient operation, high yield and good industrial application prospect. |
