This paper describes a catalytic asymmetric diamination process for terminal olefins at allylic and homoallylic carbons via formal C-H activation using di-tert-butyldiaziridinone as nitrogen source with a catalyst generated from Pd2(dba)3 and chiral phosphorus amidite ligand. A wide variety of readily available terminal olefins can be effectively diaminated in good yields with high regio-, diastereo-, and enantioselectivities.
本文描述了一种通过使用二叔丁基二氮杂环丙烷作为氮源,以Pd2(dba)3和手性磷亚胺配体生成的催化剂,经由形式上的C-H活化,对末端烯烃的烯丙基和高烯丙基碳进行催化不对称双胺化的过程。多种容易获得的末端烯烃能够以高区域选择性、非对映选择性和对映选择性,有效地进行双胺化反应,且产率良好。
