Synthesis of Chiral Amino Acid Anilides by Ligand‐Free Copper‐Catalyzed Selective
An atom‐economic, practical and cost‐effective protocol for synthesis of chiral amino acid anilides via ligand‐free copper‐catalyzed selective CN cross coupling of chiral amino acid amides and aryl halides, hetereoaryl halides and a vinyl bromide has been developed. No racemization occurred during the CN coupling. A plausible mechanism is proposed.
