Asymmetric Dearomatization of 1‑Aminonaphthalene Derivatives by Gold-Catalyzed Intramolecular Double C–C Bond Formation

It has been established that a cationic gold­(I)/axially chiral biaryl bisphosphine complex catalyzes asymmetric dearomatization of 1-aminonaphthalene derivatives by the intramolecular double C–C bond formation. Two different dearomatization products were obtained depending on the substituents on the benzyl groups at the alkyne termini.
