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。

Results The linear response range was 0.9420-18.84mg L^(-1)(r=0.9995), 1.190-23.79 mg L^(-1)(r=0.9995), 1.107-22.14 mgL^(-1)(r=0.9994), 56.78-1.136×10^3 mgL^(-1)(r=0.9990) and 0.6219-12.44 mgL^(-1)(r=0.9998), respectively (n=5). The average recoveries (n=9) of rutin, hyperin, isoquercitrin, 4, 5-O-dicaffeoyl quinic acid and isorhamnetin-3-O-glucoside were 98.1%, 100.7%, 98.4%, 100.2% and 101.7%, respectively.
结果 芦丁、金丝桃苷、异槲皮苷、4，5-O-二咖啡酰奎宁酸、异鼠李素－3-O-葡萄糖苷质量浓度分别在0.942~18.84mgL^(-1)(r=0.9995)、1.190~23.79mgL^(-1)(r=0.9995)、1.107~22.14mgL^(-1)(r=0.9994)、56.78~1.136×10^3 mgL^(-1)(r=0.9990)、0.6219~12.44mgL^(-1)(r=0.9998)内与峰面积呈良好的线性关系(n=5)；方法回收率(n=9)分别为98.1%、100.7%、98.4%、100.2%、101.7%。
