Complexes of chiral salen and its related tetradentate Schiff-base ligands adopt three different configurations, trans, cis-alpha and cis-beta. Of these complexes, trans-complexes have been widely used as catalysts for various asymmetric reactions. However, recent studies have disclosed that cis-beta metallosalen and its related complexes show unique asymmetric catalyses that cannot be achieved by trans-metallosalen complexes. The present article summarizes generation of cis-beta metallosalen and its related complexes, their structural features, and their application to asymmetric syntheses.
手性双水杨醛缩乙二胺及其相关四齿席夫碱配体的配合物呈现出三种不同的构型，即反式、顺式-α和顺式-β。在这些配合物中，反式配合物已被广泛用作各种不对称反应的催化剂。然而，最近的研究表明，顺式-β金属双水杨醛缩乙二胺及其相关配合物表现出独特的不对称催化作用，这是反式金属双水杨醛缩乙二胺配合物无法实现的。本文总结了顺式-β金属双水杨醛缩乙二胺及其相关配合物的生成、结构特征及其在不对称合成中的应用。
