  • Determination of Ring Conformation in 1-Benzyl-1,2,3,4-tetrahydroisoquinolines and a New Synthesis of the Chiral Compounds.
    作者:Tatsumi SHINOHARA、Akira TAKEDA、Jun TODA、Takehiro SANO
    DOI:10.1248/cpb.46.430
    日期:——
    The conformation of the piperideine ring in 1-benzyl-1, 2, 3, 4-tetrahydroisoquinolines was determined as 2H3 form with a pseudoaxial position of the 1-benzyl group by circular dichroism (CD) spectral comparison with 1-methyl-1, 2, 3, 4-tetrahydroisoquinolines. The chiral center at C-1 of 1, 2, 3, 4-tetrahydroisoquinoline (TIQ) was constructed in an unambiguous manner by applying a new method of TIQ synthesis utilizing the Pummerer reaction as a key step. Enantiomerically pure (R)- and (S)-1-methyl- and 1-benzyltetrahydroisoquinolines (1) were prepared starting from readily available chiral amines (2) in good overall yields.
    通过对圆二色谱(CD)的比较,确定了1-苄基-1,2,3,4-四氢异喹啉中的哌啶环构象为2H3形式,1-苄基处于假轴向位置。通过应用以Pummerer反应为关键步骤的新型四氢异喹啉(TIQ)合成方法,在C-1位上构建了TIQ的手性中心,方法明确无误。从易获得的 chiral amine(2)出发,以良好的整体产率制备了光学纯的(R)-和(S)-1-甲基和1-苄基四氢异喹啉(1)。
  • Enhancing Effects of Salt Formation on Catalytic Activity and Enantioselectivity for Asymmetric Hydrogenation of Isoquinolinium Salts by Dinuclear Halide-Bridged Iridium Complexes Bearing Chiral Diphosphine Ligands
    作者:Yusuke Kita、Kenta Yamaji、Kosuke Higashida、Kandula Sathaiah、Atuhiro Iimuro、Kazushi Mashima

    日期:2015.1.26
    Asymmetric hydrogenation of 1‐ and 3‐substituted and 1,3‐disubstituted isoquinolinium chlorides using triply halide‐bridged dinuclear iridium complexes [Ir(H)(diphosphine)}2(μ‐Cl)3]Cl has been achieved by the strategy of HCl salt formation of isoquinolines to afford the corresponding chiral 1,2,3,4‐tetrahydroisoquinolines (THIQs) in high yields and with excellent enantioselectivities after simple
    该策略已实现了使用三卤化物桥联的双核络合物[Ir(H)(diphosphine)} 2(μ-Cl)3 ] Cl的1和3,3和1,3和2,3取代的异喹啉化物的不对称氢化。简单的基础操作后,即可高产率获得异氰酸喹啉盐酸盐,从而获得相应的手性1,2,3,4-四氢异喹啉(THIQs),并具有出色的对映选择性。已通过时程实验研究了成盐的影响,结果表明,异喹啉化物的生成明显阻止了无催化活性的无核二氢三氢化物配合物的形成,这在无盐异喹啉底物的催化还原中很容易产生。基于机械调查,包括1 H和31 P 1 H} NMR研究以及几种中间体的分离和表征,阐明了异喹啉化物的阴离子的功能,这使我们能够提出一种新的涉及阴离子配位的外球机理底物形成二氢化物质,以及化物配体和底物盐的N-H质子之间的氢键。

    A new directed evolution approach is presented to enhance the activity of an enzyme and to manipulate stereoselectivity by focusing iterative saturation mutagenesis (ISM) simultaneously on residues lining the entrance tunnel and the binding pocket. This combined mutagenesis strategy was applied successfully to the monoamine oxidase from Aspergillus niger (MAO-N) in the reaction of sterically demanding
    提出了一种新的定向进化方法,通过同时将迭代饱和诱变(ISM)集中在入口通道和结合袋内的残基上来增强酶的活性并操纵立体选择性。这种组合诱变策略已成功应用于黑曲霉单胺氧化酶(MAO-N)在空间要求底物的反应中,该底物对基于苯并哌啶支架的手性药物的合成感兴趣。在( S )-1,2,3,4-四氢-1-甲基-异喹啉、( S )-1,2,3,4-四氢-1-的合成中实现了Turner型去消旋化对映选择性的逆转乙基异喹啉和( S )-1,2,3,4-四氢-1-异丙基异喹啉。广泛的分子动力学模拟表明,催化特性的改变是由于入口隧道的疏性增加与结合袋形状的改变相一致。
  • Expanded substrate scope and catalyst optimization for the catalytic kinetic resolution of N-heterocycles
    作者:Sheng-Ying Hsieh、Michael Binanzer、Imants Kreituss、Jeffrey W. Bode
    DOI:10.1039/c2cc34907h
    日期:——
    The scope, reactivity, and selectivity of the chiral hydroxamic acid-catalyzed kinetic resolution of chiral amines are improved by a new catalyst structure and a more environmentally friendly reaction protocol. In addition to increasing selectivity across all substrates, these conditions make possible the resolution of N-heterocycles containing lactams or other basic functional groups that can inhibit the catalyst.
    新型催化剂结构和更环保的反应方案改善了手性基的手性羟酸催化动力学解析的范围、反应性和选择性。除了提高对所有底物的选择性外,这些条件还使含有内酰胺或其他可抑制催化剂的碱性官能团的 N-杂环的解析成为可能。
