    New Continuous Production Process for Enantiopure (2R,5R)-Hexanediol
    摘要:
    A new continuous production process has been developed for optically active pure (2R,5R)-hexanediol. The process uses resting whole cells of Lactobacillus kefir DSM 20587 as a biocatalyst. The reduction of (2,5)-hexanedione to (2R,5R)hexanediol was carried out in a 2-L continuously operated membrane reactor. Conversion of (2,5)-hexanedione was nearly quantitative and the selectivity between product and intermediate was 78% for the product. Enantioselectivity and diastereoselectivity were >99% for the whole period. The productivity of L. kefir could be increased by factor 30. (2R,5R)-Hexanediol was continuously produced over 5 days with a space-time yield of 64 g.L-1.d(-1).

    通过使用含有乙醇脱氢 ADH-'A' 的红球菌 DSM 44541 的冻干细胞,研究了对称和非对称二酮的不对称还原以及通过生物催化氢转移对各种二醇的立体选择性氧化。(ω-1)-和 (ω-2)-位置的对称和非对称二酮被还原为具有高立体偏好的 Prelog 产物,而空间上要求更高的酮部分,例如 (ω-3)-位置的那些,保持不变。对于氧化模式,实现了伯醇和仲醇之间的区别,并且在(ω-1)-和(ω-2)-位的(S)构型的仲醇被优先氧化。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

  • Highly Efficient Synthesis of Enantiopure DiacetylatedC2-Symmetric Diols by Ruthenium- and Enzyme-Catalyzed Dynamic Kinetic Asymmetric Transformation (DYKAT)
    作者:Belén Martín-Matute、Michaela Edin、Jan-E. Bäckvall
    DOI:10.1002/chem.200600257
    日期:2006.8.7
    starting from commercially available mixtures of the diols (dl/meso approximately 1:1) has been realized by combining a fast ruthenium-catalyzed epimerization with an enzymatic transesterification. The in situ coupling of these two processes produces the diacetates in high yield in >99 % enantiomeric excess.

    A series of new HIV-1 protease inhibitors (PIs) were designed using a general strategy that combines computational structure-based design with substrate-envelope constraints. The PIs incorporate various alcohol-derived P2 carbamates with acyclic and cyclic heteroatomic functionalities into the (R)-hydroxyethylamine isostere. Most of the new PIs show potent binding affinities against wild-type HIV-1
    一系列新的 HIV-1 蛋白酶抑制剂 (PI) 是使用一种通用策略设计的,该策略将基于计算结构的设计与底物包络约束相结合。PI 将具有无环和环状杂原子官能团的各种醇衍生的 P2 氨基甲酸酯结合到 ( R )-羟乙胺等排体中。大多数新的 PI 显示出对野生型 HIV-1 蛋白酶和三种多重耐药 (MDR) 变体的有效结合亲和力。特别是,含有 2,2-二氯乙酰胺、吡咯烷酮、咪唑烷酮和 恶唑烷酮部分的抑制剂在 P2 处对K i最有效皮摩尔范围内的值。几种新的 PI 对来自 HIV-1 进化枝 A、B 和 C 以及两种 MDR 变体的患者来源的野生型病毒表现出纳摩尔级的抗病毒效力。四种有效抑制剂的晶体结构分析表明,新 P2 部分的羰基促进了与蛋白酶不变的 Asp29 残基的广泛氢键相互作用。这些构效关系的发现可用于设计具有增强的酶抑制和抗病毒效力的新 PI。

  • Biocatalytical production of (5S)-hydroxy-2-hexanone

    Biocatalytical approaches have been investigated in order to improve accessibility of the bifunctional chiral building block (5S)-hydroxy-2-hexanone ((S)-2). As a result, a new synthetic route starting from 2,5-hexanedione (1) was developed for (S)-2, which is produced with high enantioselectivity (ee >99%). Since (S)-2 can be reduced further to furnish (2S,5S)-hexanediol ((2S,5S)-3), chemoselectivity is a major issue. Among the tested biocatalysts the whole-cell system S. cerevisiae L13 surpasses the bacterial dehydrogenase ADH-T in terms of chemoselectivity. The use of whole-cells of S. cerevisiae L13 affords (S)-2 from prochiral 1 with 85% yield, which is 21% more than the value obtained with ADH-T. This is due to the different reaction rates of monoreduction (1→2) and consecutive reduction (2→3) of the respective biocatalysts. In order to optimise the performance of the whole-cell-bioreduction 1→2 with S. cerevisiae, the system was studied in detail, revealing interactions between cell-physiology and xenobiotic substrate and by-products, respectively. This study compares the whole-cell biocatalytic route with the enzymatic route to enantiopure (S)-2 and investigates factors determining performance and outcome of the bioreductions.
    为了提高双功能手性结构单元 (5S)-hydroxy-2-hexanone ((S)-2)的可及性,我们研究了生物催化方法。因此,以 2,5-己二酮 (1) 为起点的 (S)-2 新合成路线被开发出来,其生产具有很高的对映选择性(ee >99%)。由于(S)-2 可以进一步还原生成 (2S,5S)-己二醇((2S,5S)-3),因此化学选择性是一个主要问题。在测试的生物催化剂中,全细胞系统 S. cerevisiae L13 的化学选择性超过了细菌脱氢酶 ADH-T。使用全细胞 S. cerevisiae L13 从原手性 1 中生成 (S)-2 的产率为 85%,比 ADH-T 高出 21%。这是因为两种生物催化剂的单还原(1→2)和连续还原(2→3)反应速率不同。为了优化全细胞生物还原 1→2 与 S. cerevisiae 的性能,对该系统进行了详细研究,分别揭示了细胞生理学与异生物底物和副产物之间的相互作用。本研究比较了全细胞生物催化途径和酶法途径制备对映体纯(S)-2 的方法,并研究了决定生物还原的性能和结果的因素。
