Ligand-free CuI-catalyzed selective C–N coupling of aliphatic amino group of α-amino acid amides with ortho-dihaloarenes

Selective C–N coupling reaction of diaryliodonium salts and dinucleophiles

Ligand-free copper-catalyzed selective N-arylation of dinucleophiles including chiral α-amino amides with diaryliodonium salts as aryl electrophile equivalents was realized. Diaryliodonium salts prefer to react with dinucleophiles at the site of stronger basic amino groups.
