1) Four resinous catalysts (Resins A–D) for the racemization of amino acids were prepared. They had structures partially similar to that of salicylaldehyde or pyridoxal. Resins A and B were prepared by the chemical modification of o-cresol-phenol-formalin resin and salicylic acid-phenol-formalin resin respectively. Resins C and D were obtained by attaching chemically pyridoxal and salicylaldehyde residues respectively to a styrenedivinylbenzene lattice.
2) These resins catalyzed the racemization of amino acids in the presence of cupric ions at 100°C.
