The development of catalysts for intramolecular asymmetric alkene hydroamination has been investigated extensively over the past two decades, since the hydroamination is a highly atom economical process in which an amine N-H bond is added to an unsaturated carbon-carbon bond leading to the formation of nitrogen heterocycles that are building blocks in numerous biologically and pharmacologically active compounds. The organolanthanide catalysts have been shown to be promising in this area. This perspective highlights the recent progress in the development of organolanthanide catalysts with chiral biaryl-backbones for the asymmetric hydroamination/cyclization of non-activated alkenes.
在过去的二十年中,人们广泛研究了用于分子内不对称烯烃氢胺化的催化剂的发展,因为氢胺化是一种高度原子经济的过程,其中胺的 N-H 键被添加到不饱和碳-碳键中,导致形成氮杂环,这些氮杂环是许多具有生物和药理活性的化合物的构建块。有机镧系元素催化剂在这方面表现出很大的潜力。本文重点介绍了具有手性联芳骨架的有机镧系元素催化剂在非活化烯烃的不对称氢胺化/环化反应中的最新进展。
