介绍了一类新的催化剂2-氮杂三烯作为催化烯丙基胺的不对称合成的平台。在这里,我们证明了他们的承诺,通过非对映异构体的合成顺式和反式-1,2-二胺通过其铜-双(膦)催化还原偶联与亚胺。使用Ph-BPE作为支持配体,获得反式二胺(高达91%产率,>20:1 dr,和>99:1 er),并且使用很少使用的t-Bu-BDPP,产生顺式二胺(高达76%产率,1:>20 dr,和97:3 er)。
We introduce a new reagent class, 2-azatrienes, as a platform for 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 to 76% yield, 1:>20 dr, and 97:3 er).
