YieldReaction ConditionsOperation in experiment
63% With dmap; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In dichloromethane; at 20℃;Inert atmosphere; General procedure: In the presence of DMAP as the catalyst to speed up the reaction, substituted 1,3-cyclohexanediones or substituted 1,3-dimethyl-1H-pyrazol-5-ol (0.1 mol), EDCI (0.1mol), anhydrous dichloromethane (DCM) (30 mL) and compound D (0.1 mol) wereadded to a 50 mL eggplant-shaped. The solution was stirred for 5-8 h. The progress ofthe reaction was monitored by TLC. After completion of the reaction, DCM was removed from the system under reduced pressure. Residues were purified via flashchromatography (Vethylacetate: Vpetroleumether =1:3) to afford the enol ester.
