手性烯烃配体是一类具有重要应用前景的新型配体,自发展以来就引起化学家们的广泛关注.手性烯烃配体在一些反应中表现出比传统氮、磷、氧配体更高的活性和选择性,实现了一些使用其它类型配体不能实现的化学转化.为了增强手性烯烃配体与金属的配位能力,化学家们在其骨架上引入杂原子,发展得到混合型的烯烃配体,增加了配体的多样性,对进一步拓展手性烯烃配体的类型和应用具有非常重要的意义.目前关于手性烯烃配体已经有一些综述,本综述将着重介绍最近几年来发展的手性开链双烯配体、手性膦烯烃配体和手性硫烯烃配体及其在过渡金属催化的不对称反应领域的应用.
Chiral olefin ligands are a new class of ligands with important applications and have attracted a great deal of attention from chemists since their development.Chiral olefin ligands show more than traditional nitrogen, phosphorus and oxygen ligands in some reactions High activity and selectivity to achieve some chemical conversion can not be achieved using other types of ligands.In order to enhance the chiral olefin ligands and metal coordination ability, chemists in the framework of the introduction of heteroatoms, the development of mixed type Of the olefin ligands, increasing the diversity of ligands, to further expand the type and application of chiral olefin ligands is of great significance.Currently on the chiral olefin ligands have some overview, this review will highlight the recent few In recent years, the development of chiral open-chain diene ligands, chiral phosphine ligands and chiral thioolefins ligands and their applications in transition metal-catalyzed asymmetric reactions.
