Abstract

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 II was observed for TrpK.
