directing group screening to enable olefin difunctionalization with high levels of regio-, chemo-, and diastereocontrol. This general and practical protocol is compatible with α- or β-substituted terminal alkenes and internal alkenes, providing rapid access to branched aliphatic amines bearing two skipped and vicinal stereocenters with high diastereoselectivities that would otherwise be difficult to synthesize
我们在此报告了使用 Ni(II) 催化剂的烯基胺与两种不同的有机卤化物(碘化物和溴化物)的分子间顺芳基烷基化和烯基烷基化。可切割的双齿喹啉酰胺在广泛的定向基团筛选后使用,以实现具有高水平区域、化学和非对映控制的烯烃双官能化。这种通用且实用的方案与α-或β-取代的末端烯烃和内部烯烃兼容,可快速获取带有两个跳跃和邻位立体中心的支链脂肪胺,这些立体中心具有高非对映选择性,否则很难合成。
