Gold-catalyzed formation of substituted aminobenzophenone derivatives via intramolecular 6-endo-dig cyclization.

An efficient and straightforward synthetic method to access substituted aminobenzophenones has been developed. This transformation was catalyzed by gold and a new C—C bond was formed through intramolecular 6-endo-dig cyclization. The substituted aminobenzophenones were obtained in good to excellent yields.
