The enantiomeric recognition of chiral monoaza-crown ethers for amino acids as their sodium and potassium salts has been investigated by UV-vis. The highest discrimination was observed for TrpK (D/L = 6.47). The reversed enantioselectivity of chiral monoaza-crown ether ll was observed for TrpK. (c) 2005 Elsevier Ltd. All rights reserved.
