Optically Active Compounds Derived from Salicylaldehyde and Pyridoxal: Syntheses and Their Chelate Formation Properties in the Interaction with α-Amino Acid
Synthesis of chiral compounds derived from salicylaldehyde and pyridoxal was carried out.In aqueous media containing copper ion, these compounds were analyzed to form Schiff base copper chelate spontaneously with α-amino acid.This complex formation process was reversed by the addition of EDTA.Application of the compounds to the resolution of α-amino acids are discussed.
