catalytic enantioselective synthesis of allylic amines. Herein, we demonstrate their promise by a diastereodivergent synthesis of syn- and anti-1,2-diamines through their Cu–bis(phosphine)-catalyzed reductive couplings with imines. With Ph-BPE as the supporting ligand, anti-diamines are obtained (up to 91% yield, >20:1 dr, and >99:1 er), and with the rarely utilized t-Bu-BDPP, syn-diamines are generated (up
我们介绍了一种新的试剂类 2-氮杂
三烯,作为催化对映选择性合成
烯丙基胺的平台。在这里,我们通过
铜-双(膦)催化的与
亚胺的还原偶联,通过非对映异构合成顺-和反-1,2-二胺来证明它们的前景。以 Ph-BPE 作为支持
配体,得到反二胺(高达 91% 的产率,>20:1 dr,和 >99:1 er),而使用很少使用的t -Bu-B
DPP,顺二胺是生成(高达 76% 的产率,1:>20 dr 和 97:3 er)。
