Starting from diverse alkene-tethered aryl iodides and O-benzoyl-hydroxylamines, the enantioselective reductive cross-electrophilic 1,2-carboamination of unactivated alkenes was achieved using a chiral pyrox/nickel complex as the catalyst. This mild, modular, and practical protocol provides rapid access to a variety of β-chiral amines with an enantioenriched aryl-substituted quaternary carbon center
从各种烯烃系的芳基碘化物和O-苯甲酰基-羟胺开始,使用手性吡咯/镍络合物作为催化剂,可以实现未活化烯烃的对映选择性还原交亲电子1,2-碳氨基化反应。这种温和,模块化和实用的方案可快速获得具有丰富对映体和对映体选择性的,具有对映体富集的芳基取代的季碳中心的各种β-手性胺。与Pd和Cu催化相比,该过程显示出互补的区域选择性。
