"Cinchona:any of several trees and shrubs of the genus Cinchona, native chiefly to the andes and cultivated for bark that yields the medicinal alkaloids quinine and quinidine, which are used to treat malaria."

金鸡纳树：一种金鸡纳属的树木和灌木，原产于安第斯山区，其树皮含有治疗疟疾的药用生物碱奎宁和奎尼定，因而被栽植。

The proper in-situ polymerization systems of acidic and basic compounds using amino acid derivatives and cinchona alkaloids as template molecules respectively were adopted for preparation of molecularly imprinted monolithic columns by systematically investigating the effect of polymerization conditions on pore structure and selectivity of resulting polymers. The enantiomers of amino acid derivatives and the diastereomers of cinchona alkaloids were successfully resolved on these columns.

本文分别以氨基酸衍生物和辛可纳生物碱为模板分子，系统研究了制备条件对聚合物孔结构和选择性的影响，建立了合适的酸性化合物和碱性化合物的原位印迹体系。

It is demonstrated that the chiral quaternary ammonium salts catalysts exhibit promising catalytic properties for the substrate. Part III: The synthesis and the characterizing of the macroporous aminomethyl resin-supported cinchona alkaloid complexes and the study on its catalytic properties The part consists of two subsections. the macroporous aminomethyl resin -supported cinchona alkaloid complexes were synthesized by the stuff (cinchonine, quinine and macroporous aminomethyl resin). Their structures were characterized by means of elemental analysis, XPS, TG/DTA; the chiral polymer-supported complexes were first used as catalysts for the reduction of ketones. Their catalytic properties for the reduction processes were investigated. The comparison of the products e.e., the conversion of the substrate among different reduction processes was employed with determined by HPLC. The effects of the time, the temperature, the ratio of catalyst to substrate, reaction solvent as well as the recycle times were also discussed.

第三章聚-4-氨甲基苯乙烯负载金鸡纳碱金属络合物的合成与表征及其不对称催化性能研究本章分为两节，以辛可宁和奎宁及聚-4-氨甲基苯乙烯为原料，合成了4种聚-4-氨甲基苯乙烯负载金鸡纳碱络合物催化剂，并对它们的结构用元素分析、X-射线光电子能谱、TG/DTA等几种测试手段进行了表征；首次将所合成的手性高分子负载的金属络合物用于催化芳香酮不对称还原反应，详细研究了所得的手性高分子负载的金属络合物对不同底物的催化性能，用HPLC等分析手段定量检测了还原过程的底物转化率及其产物对映异构体选择性，并考察了反应时间、反应温度、催化剂和底物投料比、反应溶剂和循环次数对催化性能的影响。
