Abstract (en)
Amino acid free bases are prepared electrochemically without production of intermediate acid salts. Amino acids having reducible disulfide linkages and at least one basic nitrogen group are reduced at a high surface area, noncontaminating cathode to provide a current density of at least 50mA/cm<2>, product yield of at least 90% and an operating current efficiency of at least 90%.
