  • 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)。
  • An (<i>R</i>)-Imine Reductase Biocatalyst for the Asymmetric Reduction of Cyclic Imines

    enantiomerically pure chiral amines continues to expand, few existing methods provide access to secondary amines. To address this shortcoming, we have over-expressed the gene for an (R)-imine reductase [(R)-IRED] from Streptomyces sp. GF3587 in Escherichia coli to create a recombinant whole-cell biocatalyst for the asymmetric reduction of prochiral imines. The (R)-IRED was screened against a panel of cyclic imines
    尽管可用于合成对映体纯的手性胺的生物催化剂的范围不断扩大,但现有的方法很少能提供仲胺的途径。为了解决这个缺点,我们过量表达了链霉菌属(Streptomyces sp。)的(R)-亚胺还原酶[(R)-IRED]的基因。GF3587在大肠杆菌中创建重组全细胞生物催化剂,用于不对称还原前手性亚胺。针对一组环状亚胺和两个亚胺离子筛选了(R)-IRED,结果显示该催化剂具有较高的催化活性和对映选择性。从亚胺前体的制备规模的生物碱(R)-亚氨酸的合成规模(90%收率; 99%ee)以克为单位进行。酶活性位点的同源模型,基于来自链霉菌的紧密相关的(R)-IRED的结构,
  • Stereoselectivity and Structural Characterization of an Imine Reductase (IRED) from <i>Amycolatopsis orientalis</i>

    The imine reductase AoIRED from Amycolatopsis orientalis (Uniprot R4SNK4) catalyzes the NADPH-dependent reduction of a wide range of prochiral imines and iminium ions, predominantly with (S)-selectivity and with ee’s of up to >99%. AoIRED displays up to 100-fold greater catalytic efficiency for 2-methyl-1-pyrroline (2MPN) compared to other IREDs, such as the enzyme from Streptomyces sp. GF3546, which
    来自东方扁豆的亚胺还原酶Ao IRED(Uniprot R4SNK4)催化NADPH依赖性的一系列前手性亚胺和亚胺离子的还原,主要具有(S)选择性和ee高达99%以上。敖相对于其他的IRED,例如从酶为2-甲基-1-吡咯啉(2MPN)IRED显示高达100倍以上的催化效率链霉菌属。GF3546也具有(S)选择性,因此,Ao IRED是制备合成的有趣候选物。oIRED表现出不同寻常的催化性能,在结构相似的底物之间观察到立体选择性的转化,并且在1-甲基-3,4-二氢异喹啉的情况下,对于同一底物,取决于纯化后酶的年龄。Ao IRED的结构已在“开放”载脂蛋白中确定-形式,揭示规范的二聚体IRED折叠,其中在参与单体的N-和C-末端结构域之间形成活性位点。与NADPH的共结晶产生了与辅因子复合的“封闭”形式,其中域的相对封闭以及相关的环运动导致活性位点小得多。还可以通过与NADPH和1-甲基-1,2
  • Exploiting the Catalytic Diversity of Short‐Chain Dehydrogenases/Reductases: Versatile Enzymes from Plants with Extended Imine Substrate Scope
    作者:Sebastian Roth、Matthew B. Kilgore、Toni M. Kutchan、Michael Müller
    DOI:10.1002/cbic.201800291
    日期:2018.9.4
    One enzyme, three activities: The plant SDR noroxomaritidine reductase (NR) serves as an enone reductase in alkaloid biosynthesis. Here, we show that NR accepts different imine compounds and features a keto reductase activity. With NR as a template, we have identified a novel imine‐reducing SDR.
    一种酶,具有三种活性:植物SDR诺马曲啶还原酶(NR)在生物碱生物合成中充当烯酮还原酶。在这里,我们表明NR接受不同的亚胺化合物,并具有酮还原酶活性。以NR为模板,我们确定了一种新型的减少亚胺的SDR。
  • Crossing the Border: From Keto‐ to Imine Reduction in Short‐Chain Dehydrogenases/Reductases
    作者:Sebastian Roth、Peter Stockinger、Jakob Steff、Simon Steimle、Viktor Sautner、Kai Tittmann、Jürgen Pleiss、Michael Müller
    DOI:10.1002/cbic.202000233
    日期:2020.9.14
    Willing to learn: In the context of enzymatic asymmetric reduction SDRs are mainly known for their ability to reduce ketones, rather than imines. However, both activities are based on the same catalytic triad. Using a rational approach inspired by two imine‐reducing SDRs, the keto‐reducing M77_SDR was equipped with imine‐reducing capability.
    愿意学习:在酶促不对称还原的背景下,SDR 主要因其还原酮而非亚胺的能力而闻名。然而,这两种活性都基于相同的催化三联体。采用受两种亚胺还原 SDR 启发的理性方法,酮还原M 77_SDR 配备了亚胺还原能力。
