| titleOfInvention | One-pot two-step method for synthesizing coumarin-3-carboxylic acid compounds |
| abstract | The invention relates to a method for synthesizing coumarin-3-carboxylic acid compounds by a one-pot two-step method, and the structural formula of the coumarin-3-carboxylic acid compounds is: Wherein R 1 is H-, Cl-, Br, NO 2- , CH 3- , HO-; The synthetic process of described coumarin-3-carboxylic acid compound is: Using malonic acid, acetone and substituted salicylaldehyde as raw materials, iodine as catalyst, and acetic anhydride as solvent, a series of coumarin-3-carboxylic acid compounds are synthesized by one-pot series reaction, and the efficiency and yield are relatively different. Footwork has been greatly improved. |
