efficient dinuclear copper complexcatalyzed Friedel–Crafts reaction has been demonstrated for the alkylation of 1-naphthol using N-tosyl aldimine. In this context, various chiral amino alcohol derived Schiff base ligands with different achiral and chiral linkers were synthesized and their copper (II) complexes were generated in situ. One of the dinuclear copper complexes with chiral linker has emerged

An organocatalytic enantioselective Friedel Crafts reaction of 1-naphthols with aldimines has been developed. The method affords a direct access to chiral aminoarylnaphthols in good yields and with good to high enantioselectivities.
Asymmetric Aza-Friedel-Crafts Reaction of 2-Naphthol with Tosylimines Catalyzed by a Dinuclear Zinc Complex
The first asymmetric aza-Friedel-Crafts reaction of 2-naphthol with tosylimines was developed via a dinuclear zinc catalyst (up to 98% ee). It provided a new method for the asymmetric synthesis of Betti base derivatives.
