Abstract

Asymmetric catalytic reactions, in which diverse enantioselective catalysts have been developed for maximizing turnover number and enantiomeric excess, serve as the cornerstone strategy for achieving molecular stereoselectivity in fine chemicals and pharmaceutical industry. In recent years, chiral metal nanoclusters (NCs) have emerged as a cutting-edge research frontier in asymmetric catalysis due to their precisely tunable structural attributes at the unprecedented atomic level, as well as their hierarchical structures reminiscent of natural proteins. It has become known that chirality can emerge at diverse structural hierarchies, including metal core, metal-ligand interface, ligand body, and assembly patterns of metal NCs, offering an ideal platform to not only boost the catalytic activity but also understand the catalytic mechanism in asymmetric reactions. This review systematically summarizes recent progress in the synthesis and asymmetric catalytic applications of chiral metal NCs, based on their core-shell structure scheme. The discussion starts with a brief elaboration on the structural origin of cluster chirality, followed by a concise account of the synthetic methodologies delivering enantiopure metal NCs. Before concluding this review with our perspectives on metal NCs-based asymmetric catalysis, the catalytic applications of chiral metal NCs are outlined. The fundamental and applicable advances summarized in this review should be useful for designing chiral metal NCs for asymmetric catalytic applications.

金属纳米团簇的层次手性促进了不对称催化
在不对称催化反应中,各种对映体选择性催化剂被开发出来,以最大限度地提高周转数和对映体的过剩,是精细化工和制药工业中实现分子立体选择性的基石策略。近年来,手性金属纳米团簇(NCs)由于其在空前的原子水平上具有精确可调的结构属性以及令人联想到天然蛋白质的层次结构而成为不对称催化研究的前沿。手性可以出现在金属核、金属配体界面、配体和金属nc的组装方式等不同的结构层次上,为提高催化活性和了解不对称反应的催化机理提供了理想的平台。本文系统地综述了近年来基于核壳结构的手性金属纳米碳化合物的合成及其不对称催化应用的研究进展。讨论首先简要阐述了簇手性的结构起源,然后简要介绍了提供对映纯金属NCs的合成方法。在对金属NCs基不对称催化的研究进展进行总结之前,对手性金属NCs的催化应用进行了概述。本文综述了手性金属纳米材料在不对称催化方面的研究进展,对设计手性金属纳米材料具有一定的指导意义。
