  • Highly Diastereo- and Enantioselective Ir-Catalyzed Hydrogenation of 2,3-Disubstituted Quinolines with Structurally Fine-Tuned Phosphine–Phosphoramidite Ligands
    作者:Xin-Hu Hu、Xiang-Ping Hu
    DOI:10.1021/acs.orglett.9b03925
    日期:2019.12.20
    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。
  • A new electronically deficient atropisomeric diphosphine ligand (S)-CF3O-BiPhep and its application in asymmetric hydrogenation

    日期:2012.5
    A new electronically deficient atropisomeric diphosphine ligand (S)-CF3O-BiPhep was synthesized from 1-bromo-3-(trifluoromethoxy)benzene in high yield. The key steps included oxidative coupling with anhydrous ferric chloride and optical resolution by (+)-DMTA. The ligand afforded high performance for Ir-catalyzed asymmetric hydrogenation of quinolines with ee up to 92% and TON up to 25,000. It was

  • A one-pot process for the enantioselective synthesis of tetrahydroquinolines and tetrahydroisoquinolines <i>via</i> asymmetric reductive amination (ARA)
    作者:Tao Yang、Qin Yin、Guoxian Gu、Xumu Zhang
    DOI:10.1039/c8cc03586e
    日期:——
    Asymmetric reductive amination for the synthesis of both chiral tetrahydroquinolines (THQs) and tetrahydroisoquinolines (THIQs) has been realized with an Ir/ZhaoPhos catalytic system via a one-pot N-Boc deprotection/intramolecular asymmetric reductive amination (ARA) sequence. Control experiments reveal that HCl plays a vital role to the success of this transformation. The HCl acid assists the removal
    Ir / ZhaoPhos催化体系通过一锅N - Boc脱保护/分子内不对称还原胺化(ARA)序列实现了用于合成手性四氢喹啉(THQs)和四氢异喹啉(THIQs)的不对称还原胺化。对照实验表明,HCl对这种转化的成功起着至关重要的作用。HCl酸有助于除去N- Boc保护基,还提供氯离子与ZhaoPhos中的硫脲部分相互作用,从而实现出色的反应对映控制。

    DOI:10.1002/ejoc.201100981
    日期:2011.12
    preparation of tetrahydroquinolines has been developed. The procedure involves a highly regio-and enantioselective intermolecular iridium-catalyzed allylic amination followed by one-pot hydroboration and intramolecular Suzuki-Miyaura cross-coupling. This method was applied in total syntheses of the alkaloids (+)-angustureine and (-)-cuspareine.
