Silver-Catalyzed Three-Component Coupling of Carbon Dioxide, Amines and α-Diazoesters

A silver-catalyzed three-component coupling reaction of carbon dioxide, amines and -diazoesters has been developed for the first time. The novel reaction provides an efficient and practical methodology for the synthesis of a wide range of new -carbamoyloxy esters, which are difficult to prepare by existing methods. The advantages of the method include the use of readily available starting materials, simple catalytic system, good atom economy and high functional group tolerance.
