for the palladium-catalyzed Suzuki-Miyaura and carbonyl enolate coupling of unactivated aryl arenesulfonates was developed utilizing XPhos, 1, and Pd(OAc)2. This is of significant interest because aryl tosylates and aryl benzenesulfonates are more easily handled and considerably less expensive than aryl triflates. This catalyst system effects the coupling of a variety of aryl, heteroaryl, and extremely

structures. Not surprisingly, the tendency of these compounds to undergo rapid hydrolysis has complicated their synthesis. Although standard methods for amide bond formation have been used, such routes often proceed in poor yields or are accompanied by difficulty in product isolation.1 In this paper, we describe a solution to the problem of bridged bicyclic lactam synthesis that utilizes the acid-promoted
