An efficient palladium-catalyzed ortho-alkoxylation of N-benzoyl α-amino acid derivatives at roomtemperature has been explored. This novel transformation, using amino acids as directing groups, Pd(OAc)2 as catalyst, alcohols as the alkoxylation reagents, and PhI(OAc)2 as the oxidant, showed wide generality, good functional tolerance, and high monoselectivity and regioselectivity.

The nickel(II)-catalyzed ortho-arylation of unactivated C–H bonds utilizing amino acids as directing groups with aryl iodides or bromides as coupling electrophiles is described. This protocol features excellent mono-selectivity, good regioselectivity, and wide functional group tolerance. Additionally, the obtained products bearing a biaryl motif and an amino acid represent bioactive molecules with
