A chiral monoaza-15-crown-5 ether derivative was prepared from l-Leucinol and used as a chiral stationary phase. The new chiral stationary phases CSP-1 and CSP-2 were employed in separating the enantiomers of the sodium and potassium salts of amino acids. The sodium and potassium salt of the d-enantiomers of all amino acids (PhyAlaNa, PhyAlaK and PhyGlyNa, PhyGlyK, and TrpNa, TrpK) show higher selectivity
由1-亮氨酚制备手性单氮杂-15-冠-5醚衍生物,并将其用作手性固定相。使用新的手性固定相CSP- 1和CSP- 2分离氨基酸的钠盐和钾盐的对映体。所有氨基酸(PhyAlaNa,PhyAlaK和PhyGlyNa,PhyGlyK和TrpNa,TrpK)的d对映体的钠盐和钾盐对CSP- 1和CSP- 2的选择性都高于l对映体。
