| titleOfInvention | A kind of caronic acid diester compound and caronic acid derivative synthetic method |
| abstract | The invention relates to a method for synthesizing a caronate diester compound and a caronate derivative, belonging to the technical field of organic synthesis. The method for synthesizing dimethyl caronate is as follows: 1) using α-haloacetate Reacting with triphenylphosphine to prepare a phosphonium ylide intermediate; 2) reacting the phosphonium ylide intermediate obtained in step 1) with a 3,3-dimethacrylic acid derivative to obtain a caronic acid diester compound; the caronic acid derivative The compound is obtained by the reaction of the above-mentioned carronic acid diester compound with tetrabutylammonium bromide. The present invention utilizes cheap α-halogenated acetates such as ethyl methyl bromoacetate and methyl chloroacetate to react with triphenylphosphine to prepare phosphine ylides, and then reacts with cheap 3,3-dimethacrylic acid derivatives such as: 3, 3-methyl dimethacrylate and ethyl ester are reacted to obtain a caronic acid diester compound, which is then used as a raw material to prepare a caronic acid derivative. 1. The raw materials are easy to obtain and cheap and can be obtained in large quantities, 2. The reaction path is short, 3. No dangerous reactions are involved, and the production safety factor is high. |
