It has been established that a cationic gold(I)/axially chiral biaryl bisphosphine complex catalyzes asym. dearomatization of 1-aminonaphthalene derivs. by the intramol. double C-C bond formation [e.g., I 竊�ipso/ortho product II (67% yield, 87% ee) + ipso/para product III (23% yield, 44% ee)]. Two different dearomatization products were obtained depending on the substituents on the benzyl groups at the alkyne termini. [on SciFinder(R)]
