Synthesis of Substituted Naphtho-Ferrocenes via a Gold(I)-Catalyzed Intramolecular 6-endo-Dig Cyclization

Abstract

A novel series of naphtho-ferrocene derivatives were synthesized in high yields by an efficient gold-catalyzed intramolecular 6-endo-dig cyclization strategy. The salient features of this reaction include easy operation, broad substrate scope, high yields, mild conditions and it works well in wet solvent under air at room temperature.
