  diastereo- and enantioselective Ir-catalyzed hydrogenation of unfunctionalized 2,3-disubstituted quinolines, especially 3-alkyl-2-arylquinolines, has been realized. The success of this hydrogenation is ascribed to the use of a structurally fine-tuned chiral phosphine-phosphoramidite ligand with a (Sa)-3,3'-dimethyl H8-naphthyl moiety and (Rc)-1-phenylethylamine backbone. The hydrogenation displayed broad

  已经实现了高度非对映和对映选择性的Ir催化的未官能化的2，3-二取代喹啉，特别是3-烷基-2-芳基喹啉的氢化。该氢化的成功归因于使用具有（Sa）-3，3'-二甲基H8-萘基部分和（Rc）-1-苯基乙胺主链的结构精细调节的手性膦-次膦酸酯配体。氢化显示出宽泛的官能团耐受性，因此可提供高达96％ee的多种旋光性2,3-二取代的四氢喹啉，并具有完美的顺-非对映选择性。
