Preparation of High Performance Asymmetric Catalyst Using the Regularity of the Crystalline Inorganic Solid

为制备一种实用的不对称合成，设计了一种新型催化剂体系。在规则的无机固体表面形成不对称球是制备高性能不对称催化剂的重要手段。根据结晶固体的特性，对两种体系进行了研究。一是利用固体载体的离子交换能力将含光学活性胺的有机催化剂固定在蒙脱土上。另一个是固体表面原子与活性中心的配位，其中固体充当大配体。

Newly designed catalyst system was developed for preparation of a practical asymmetry synthesis. For preparation of the high performance asymmetric catalyst, asymmetric sphere formed on the surface of regularity inorganic solids is important. Two kinds of the system were examined based on the characteristic of crystalline solid. One was immobilization of the organic catalyst containing the optically active amines to montmorillonite through the ion exchange ability of the solid support. Another was the coordination of the surface atoms of the solid to the active center, in which the solid acted as a macroligand.
