Gold-Catalyzed Addition of Carbon Nucleophiles to Propargyl Carboxylates
摘要:
Propargyl carboxylates react with 1,3-dicarbonyl compounds and electron-rich arenes in the presence of Au(l) catalysts to give enol carboxylates via alpha,beta-unsaturated Au(l) carbenes or Au(l)-coordinated allenes formed by 1,2- or 1,3-acyl migration, respectively.
