    摘要:
    (R)-Ketone-cyanohydrins (R)-2 are obtained with high enantioselectivity from aliphatic ketones 1 and HCN in organic solvents using (R)-oxynitrilase (EC 4.1.2.10) as catalyst. Acid catalyzed hydrolysis of the cyanohydrins (R)-2 affords the corresponding (R)-alpha-hydroxy-alpha-methyl-carboxylic acids (R)-3 without measurable racemization.

  • A new (R)-hydroxynitrile lyase from Prunus mume: asymmetric synthesis of cyanohydrins
    作者:Samik Nanda、Yasuo Kato、Yasuhisa Asano
    DOI:10.1016/j.tet.2005.08.105
    日期:2005.11
    A new hydroxynitrile lyase (HNL) was isolated from the seed of Japanese apricot (Prunus mume). The enzyme has similar properties with HNL isolated from other Prunus species and is FAD containing enzyme. It accepts a large number of unnatural substrates (benzaldehyde and its variant) for the addition of HCN to produce the corresponding cyanohydrins in excellent optical and chemical yields. A new HPLC
    从日本杏(Prunus mume)的种子中分离出一种新的羟腈裂解酶(HNL )。该酶与从其他李属物种中分离的HNL具有相似的特性,并且是含FAD的酶。它接受大量非天然底物(苯甲醛及其变体)以添加HCN,从而以优异的光学和化学收率生产相应的氰醇。针对该酶开发了一种新的基于HPLC的对映选择性测定技术,该技术可促进在缓冲溶液(pH = 4.5)中将KCN添加到苯甲醛中。
  • Synthesis of Aliphatic and α-Halogenated Ketone Cyanohydrins with the Hydroxynitrile Lyase from <i>Manihot esculenta</i>

    日期:2014.4
    The potential of the hydroxynitrile lyase from Manihot esculenta towards ketone substrates was investigated. It was observed that the length of the aliphatic chain is a key parameter for the conversion of aliphatic, non‐branched ketones. Smaller substrates are readily converted with high enantioselectivites, but the elongation of the chain length causes a significant loss in enzyme activity. For a
    研究了来自Manihot esculenta的羟腈裂解酶对酮底物的潜力。据观察,脂族链的长度是脂族非支链酮转化的关键参数。较小的底物容易被高对映体选择物转化,但是链长的延长导致酶活性的显着降低。对于许多卤代,在此尤其是氟化的苯乙酮衍生物,已经合成了具有良好至中等对映选择性的相应的氰醇。
  • Approach to(R)- and (S)-ketone cyanohydrins using almond and apple meal as the source of (R)-oxynitrilase
    作者:Eero Kiljunen、Liisa T. Kanerva
    DOI:10.1016/s0957-4166(97)00110-9
    日期:1997.5
    The synthesis of aliphatic and aromatic (R)-ketone cyanohydrins through the addition of hydrogen cyanide to the corresponding ketones and the synthesis of the (S)-enantiomers through the kinetic resolution of racemic ketone cyanohydrins has been studied in the presence of almond or apple meal. Substrate tolerance of the (R)-oxynitrilases towards ketones ((RRC)-R-1-C-2=O) is highly restricted compared to that of structurally similar aldehydes, reactivity following the order of H>Me much greater than Et for R-2. In the case of aromatic methyl ketones reactivity difference (C6H5 much greater than p-Me-C6H4 for R-1) is notable. (C) 1997 Elsevier Science Ltd.
