    • Enantioseparation methods using chemical compounds which contain the chiral 9,11-substituted-10,11-dihydro-cinchonan skeleton (9,11-Subst.-DHC) and the precursors thereof with the 9-substituted cinchonan skeleton (9-Subst.-C) are described and discussed. The chiral compounds of the present invention are based on cinchonan derivatives containing amide structure elements which support effectively and co-operatively the enantioseparation of chiral acidic selectands involving also ion-pair and ion-exchange binding mechanism between the strong amino group of the selector and the acidic group of the selectand. The methods of enantioseparation of the present invention are related to stereoselective liquid-liquid and liquid-solid type extraction principles and fractionated crystallization employing cinchonan derivative type selectors. In one embodiment of the present invention the chiral selector is immobilized onto support material or is incorporated within a polymer or is part of a polymer used for liquid-solid enantioseparation techniques.
    • 使用含有手性9,11-取代-10,11-二氢 - 辛可诺骨架(9,11-对 - DHC)的化合物和其9-前体与9-取代的辛可诺骨架(9-对 - C)进行了描述和讨论。 本发明的手性化合物是基于含有酰胺结构元件的肉桂酸衍生物,其有效和可操作地支持手性酸性选择素的对映体分离,其还涉及选择剂的强氨基与选择剂的强氨基之间的离子对和离子交换结合机制 酸性组的选择。 本发明的对映体分离方法涉及立体选择性液体 - 液体和液体 - 固体萃取原理,并且使用辛醌衍生物型选择器进行分级结晶。 在本发明的一个实施方案中,手性选择剂被固定在载体材料上,或者被结合到聚合物中,或者是用于液体 - 固体对映体分离技术的聚合物的一部分。
