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

Abstract

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.
