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.
