Disclosed herein is a copper(II)-mediated chelation-assisted intermolecular amination of inert C(sp3)H bonds using simple alkylamines as the amino source. A straightforward and step-economic alternative to α,α-disubstituted β-amino acid derivatives is provided consequently. This reaction features good functional group tolerance and relatively broad substrate scope. Furthermore, a coupling product between
本文公开了使用简单烷基胺作为氨基源的铜(II)介导的惰性C(sp 3)H键的螯合分子间胺化反应。因此,提供了α,α-二取代的β-氨基酸衍生物的直接且经济的步骤。该反应具有良好的官能团耐受性和相对较宽的底物范围。此外,吗啉和自由基抑制剂的2,6-二-之间的偶联产物叔丁基- p甲酚(BHT)分离,表明单电子转移(SET)进程可能在这一转变有关。
