Organocatalytic Enantioselective Friedel−Crafts Reactions of 1-Naphthols with Aldimines
摘要:
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.

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

Cinchona alkaloid derivatives as organocatalysts were applied in the asymmetric aza‐Friedel–Crafts reaction of α‐naphthol with aryl aldimines. The desired chiral aminoarylnaphthols were obtained in 85% enantiomeric excess.
