| titleOfInvention | Synthesis method of beta-chloroacid ester and alpha, beta-unsaturated acid ester compound |
| abstract | The invention belongs to the technical field of organic chemistry, and particularly relates to a method for synthesizing beta-chloroacid ester and alpha, beta-unsaturated acid ester compounds. The structure of the compound 1 H NMR、 13 C NMR was characterized and confirmed. The method of the invention is that acetonitrile is used as a solvent, alkene, clorox acid monoester and 2, 6-lutidine are cracked to generate alkoxy acyl free radical by the clorox acid monoester under the photocatalysis conditionThe body and olefin generate free radical addition reaction to generate carbon free radical, then generate chlorination reaction to obtain beta-chloroate ester compound, and generate dehydrochlorination reaction under the DBU condition to generate alpha, beta-unsaturated acid ester compound. The preparation method of the compound has the advantages of starting from olefin, mild conditions, simplicity, high efficiency, strong functional group compatibility and wide application range of substrates, and can synthesize various beta-chloroacid ester and alpha, beta-unsaturated acid ester compounds from highly commercialized raw materials. The target product can be obtained with better yield based on the photoreaction of fluid chemistry, and the method has good industrial and pharmaceutical chemical application values. |
