A new phosphoramidite ligand was used in the iridium-catalyzed allylic substitution reaction. This permitted high regio- and enantioselectivities on a wide variety of substrates and nucleophiles. Because of the stereospecificity of the reaction obtained by using branched substrates, a kinetic resolution reaction was attempted. The origin of the impressive efficiency of this ligand in terms of kinetics
在铱催化的烯丙基取代反应中使用了新的亚磷酰胺配体。这允许在多种底物和亲核试剂上具有很高的区域和对映选择性。由于通过使用支链底物获得的反应的立体特异性,尝试进行动力学拆分反应。详细研究了该配体在动力学方面令人印象深刻的效率的起因,以及取代基在胺部分邻位中的作用。
