Incorporation of carbon dioxide into molecules of acetylene hydrocarbons on heterogeneous Ag-containing catalysts

The reaction between 2-(2-phenylethynyl)aniline and carbon dioxide on heterogeneous Ag-containing catalysts can lead either to benzoxazine-2-one or to 4-hydroxyquinoline-2(1Н)-one, depending on the reaction conditions (nature of the base, CO2 p

Silver-catalyzed incorporation of carbon dioxide into o-alkynylaniline derivatives

Benzoxazine-2-one derivatives are important heterocycle structures because of their various pharmaceutical activities, though their synthetic methods had been limited. In some cases, toxic reagents, such as phosgene or carbon monoxide, are required. It was found that a silver catalyst successfully promoted the incorporation of CO2 into o-alkynylanilines to afford the corresponding benzoxazine-2-ones bearing Z exo-olefin via 6-exo-dig cyclization at the activated C-C triple bond.
