Özet
The chiral monoaza-15-crown-5 ethers 4 and 5 were prepared from L-phenylalaninol and L-leucinol, respectively. The molecular recognition of these chiral crown ethers for L-amino acid ethyl esters was characterised by UV-visible spectroscopy. Binding constants (K-a), free-energy changes (-DeltaGdegrees), enthalpy changes (DeltaH) and entropy change (DeltaS) values were determined for hosts 4 and 5 with L-amino acid ethyl ester hydrochlorides in CHCl3.
