Transition-metal-functionalized ordered mesoporous silicas: an overview of sustainable chiral catalysts for enantioselective transformations

Transition-metal-catalyzed asymmetric reactions have been demonstrated to be powerful methods for enantioselective construction of various optically pure compounds. The development of ordered mesoporous silica-supported chiral transition-metal-based catalysts and the exploration of their applications represent important progress in green chemistry since such an approach enables an eco-friendly and sustainable catalytic process. In this review, we focus on recent advances in the preparation of ordered mesoporous silica-supported chiral transition-metal-based catalysts and their applications in enantioselective transformations. Firstly, we provide a brief introduction to the modification of ordered mesoporous silicas. We then present in detail, the application of transition-metal-functionalized ordered mesoporous silicas for enantioselective transformations according to various types of reactions. Lastly, prospects for the further development of this research area are discussed. This review focuses on the development of ordered mesoporous silica-supported chiral transition-metal-based catalysts for enantioselective transformations.
