A class of axially chiral pyridoxamines bearing a lateral amine arm exhibited high catalytic activity and excellent enantioselectivity in asymmetric transamination of α-keto acids, to give various α-amino acids in very good yields and with high ee's. The lateral amine arm likely participates in cooperative catalysis as the Lys residue does in biological transamination and enhances both the activity and the enantioselectivity.
