An efficient gold-catalyzed synthesis of substituted 3-methylene-3,4-dihydrobenzo[b]oxepinones from ortho-O-propargyl substituted aryl enaminones has been achieved. In this transformation a new C-C bond formation occurred reginselettively via 7-exo-dig cyclization. Benzoox-epinone derivatives were obtained in goad to excellent yields in a one-pot synthesis at ambient temperature.
