| titleOfInvention | Synthetic method of a class of α-tertiary nitrile structure β-dicarbonyl compounds |
| abstract | The invention provides a method for synthesizing a class of α-tertiary nitrile structure β-dicarbonyl compounds. The carbon-carbon coupling reaction of azobisisobutyronitrile (AIBN) and β-ketoester is used in the catalysis of cheap hydrated copper nitrate. β-dicarbonyl compounds containing α-tertiary nitrile structures that cannot be synthesized by other methods are generated in the following step, and continuous tertiary and quaternary carbon atom centers are constructed in one step. The method of the invention has good functional group tolerance, avoids the use of excessive strong bases and the pre-bromination of cyanoalkylation reagents, and at the same time, the reaction conditions are mild, the operation is simple, and is suitable for industrialization. |
