A convenient and improved procedure for the cyanation of enamines and 1,3-dicarboxyl compounds

10.1080/00397919408010246

The research focuses on developing an efficient method for the cyanation of enamines and 1,3-dicarbonyl compounds. The purpose of this study is to improve upon existing cyanation procedures, which often suffer from limitations such as toxicity, accessibility issues, thermal instability, or low yields. The researchers utilized acyl-substituted cyanatobenzenes and cyanatoanthraquinones as cyanating agents to react with enamines and 1,3-dicarbonyl compounds. The results demonstrated that this method yields good to excellent yields of the desired cyanoenamines and cyanoketones. The process involves treating enamines with the cyanating agents at room temperature, followed by hydrolysis to obtain the cyanoketones.
