Özet
A practical synthesis of chiral amine precursors 3 and 4 and chiral diaza 18-crown-6 ethers 5, 6 and 7 starting from chiral amines are reported. The molecular recognition of these chiral crown ethers for amino acids potassium and sodium salts has been characterized by UV–vis. The selectivity order is Phe>Thr>Ala. In the case of 6 the cavity of the macrocycle plays an important role in recognition.
