The design and synthesis of a new chiral monodentate spiro phosphoramidite ligand based on a hexamethyl-1,1′-spirobiindane scaffold has been accomplished. The ligand could serve as an elegant chiral monodentate ligand in the Pd-catalyzed asymmetric hydroamination/arylation of alkenes leading to chiral imidazolidin-2-ones with good enantioselectivities.
基于六甲基-1,1'-螺双茚满骨架的新型手性单齿螺亚磷酰胺配体的设计与合成已经完成。该配体可以在Pd催化的烯烃的不对称加氢/芳构化反应中用作优雅的手性单齿配体,从而产生具有良好对映选择性的手性咪唑烷-2-酮。
