The effective synthesis of chiral compounds in a highly enantioselective manner is obviously attractive. Inspired by the enzymatic reactions that occur in pocket‐like cavities with high efficiency and specificity, chemists are seeking to construct catalysts that mimic this key feature of enzymes. Recent progress in supramolecular coordination chemistry has shown that metal–organic cages (MOCs) and metal–organic frameworks (MOFs) with chiral confined cavities/pores may offer a novel platform for achieving asymmetric catalysis with high enantioselectivity. The inherent chiral confined microenvironment is considered to be analogous to the binding pocket of enzymes, and this pocket promotes enantioselective transformations. This work focuses on the recent advances in MOCs and MOFs with chiral confined spaces for asymmetric catalysis, and each section is separated into two parts based on how the chirality is achieved in these metal–organic architectures. A special emphasis is placed on discussing the relationship between the enantioselectivity and the confined spaces of the chiral functional MOCs and MOFs rather than catalytic chemistry. Finally, current challenges and perspectives are discussed. This work is anticipated to offer researchers insights into the design of sophisticated chiral confined space‐based metal–organic architectures for asymmetric catalysis with high enantioselectivity.

金属有机建筑手性密闭空间内的不对称催化。

以高度对映选择性的方式有效合成手性化合物显然是有吸引力的。受口袋状腔体中发生的高效高特异性的酶促反应的启发,化学家正在寻求构建可模仿酶这一关键特征的催化剂。超分子配位化学的最新进展表明,具有手性约束腔/孔的金属有机笼(MOC)和金属有机骨架(MOF)可能为实现高对映选择性的不对称催化提供一个新颖的平台。固有的手性受限的微环境被认为类似于酶的结合口袋,并且该口袋促进对映选择性转化。这项工作着眼于MOC和具有手性密闭空间的MOF的最新进展,用于不对称催化,根据这些金属-有机体系结构中手性的实现方式,每个部分分为两部分。特别强调讨论手性功能性MOC和MOF的对映选择性与密闭空间之间的关系,而不是催化化学。最后,讨论了当前的挑战和观点。预期这项工作将为研究人员提供深刻的见解,以进行复杂的手性受限空间基金属有机结构的设计,以实现高对映选择性的不对称催化。最后,讨论了当前的挑战和观点。预期这项工作将为研究人员提供深刻的见解,以进行复杂的手性受限空间基金属有机结构的设计,以实现高对映选择性的不对称催化。最后,讨论了当前的挑战和观点。预期这项工作将为研究人员提供深刻的见解,以进行复杂的手性受限空间基金属有机结构的设计,以实现高对映选择性的不对称催化。
