N-Arylation
Preparation of N-Aryl Compounds by Amino Acid-Promoted Ullmann-Type Coupling Reactions. — α-Amino acids promote Ullmann-type coupling reactions of either
themselves or some other N-containing reagents with aryl halides. Thus, these reactions
to can occur at relative low temperatures. They give the corresponding N-aryl α-amino
acids, aryl amines, N-arylpyrroles, -indoles, and pyrazoles, and aryl azides in good to
excellent yields. — (CAI, Q.; ZHU, W.; ZHANG, H.; ZHANG, Y.; MA*, D.;
