A chiral phosphoric acid catalyzed asymmetric transfer hydrogenation of aromatic amines, quinolin-3-amines, was successfully developed with up to 99% ee. To supplement our previous work on the Ir-catalyzed asymmetric hydrogenation of 2-alkyl substituted quinolin-3-amines, a number of 2-aryl substituted substrates were reduced to provide a series of valuable chiral exocyclic amines with high diastereo-
成功开发了手性磷酸催化芳香胺(喹啉-3-胺)的不对称转移加氢反应,其ee最高可达99%。为了补充我们先前关于2-烷基取代的喹啉-3-胺的Ir催化不对称氢化的工作,还原了许多2-芳基取代的底物,以提供一系列有价值的具有高非对映异构和对映选择性的手性环外胺。
