Diketo- and pyridine-containing chiral crown ligands having at least two chiral bulky groups attached to two different chiral carbon atoms of the crown that are covalently bonded to or coated on suitable solid supports, and further coated by hydrophobic organic solvents are disclosed. These compositions and associated methods are characterized by selectivity of several target amine or amino acid enantiomers over their counter-enantiomers and derivatives. The composition preferably has an &agr;-value greater than or equal to 4. This allows for the separation of such enantiomers with non-chromatographic resin bed separations of three separation stages or less.
本发明揭示了至少具有两个手性笨重基团附着在皇冠的两个不同手性碳原子上的含二酮和吡啶的手性冠配体,这些基团与适当的固体支持体共价键合或涂覆,并进一步被疏水有机溶剂涂覆。这些组合物和相关方法的特征是在它们的对映异构体和衍生物中选择性地选择几个目标胺或氨基酸对映异构体。该组合物的α值最好大于或等于4。这允许通过三个或更少的非色谱树脂床分离阶段分离这些对映异构体。
