摘要/Abstract

环糊精是一种通过α-1，4-糖苷键将D-吡喃葡萄糖单元连接在一起而形成的环状低聚糖，具有“内疏水、外亲水”的刚性锥形空腔结构.正是由于这个独特的“内疏水、外亲水”空间结构，使得环糊精从被发现以来，越来越受到科学工作者的关注.过渡金属催化剂作为重要的工业催化剂，与环糊精体系结合可同时发挥金属的催化性能和环糊精的分子识别和相转移等功能，极大地改善其催化性能.主要综述了环糊精参与的过渡金属催化的有机化学反应，以金属价态分类介绍了常见的0至4价过渡金属参与催化的有机反应，并对环糊精参与的金属共催化体系的未来发展前景进行了展望，预计今后该催化体系将会有更广阔的应用，不断开发出更加高效和更有选择性的催化系统.

Cyclodextrin is a kind of cyclic oligosaccharide which is composed of the D-pyran glucose units connected with the α-1,4-glycosidic bond. Cyclodextrin has the rigidly tapered cavity of hydrophobic inner and hydrophilic outer. Cyclodextrin has been attracted more and more attention from scientists since it was discovered, owning to its special space cavity of hydrophilic inner and hydrophilic outer. As an important industrial catalyst, transition metal catalyst can combine with the cyclodextrin system to simultaneously exert the catalytic properties of the metal and the molecular recognition and phase transfer of cyclodextrin, which greatly improves its catalytic performance. In this paper, the transition metal catalyzed organic reactions involving cyclodextrin are reviewed, and these reactions are described in terms of the metal valence from 0 to 4. Finally, the development and foreground of these co-catalyst systems involving metal and cyclodextrin are prospected. It is expected that the catalytic system will have a wider application in the future, and a more efficient and selective catalytic system will be continuously developed.
