  • Asymmetric carboncarbon bond forming reactions catalyzed by chiral Schiff base—titanium alkoxide complexes
    作者:Masahiko Hayashi、Tetsuya Inoue、Yasunori Miyamoto、Nobuki Oguni
    DOI:10.1016/s0040-4020(01)89374-1
    日期:1994.4
    The enantioselective addition of trimethylsilyl cyanide to a variety of aldehydes proceeded by the aid of a catalyst prepared in situ from titanium tetraisopropoxide [Ti(O-i-Pr)4] and chiral Schiff bases and gave the corresponding cyanohydrins in high optical yield (up to 96% e.e.). A remarkable rate enhancement was brought about by the addition of the Schiff base to the titanium alkoxide mediated
    在由四异丙醇[Ti(O- i- Pr)4 ]和手性席夫碱原位制备的催化剂的帮助下,将三甲基甲硅烷化物对映选择性加成到各种醛中,从而以高光学收率得到了相应的醇(最多到96%ee)。通过将席夫碱加入到醇盐介导的醛的甲硅烷化中,可以显着提高速率。该催化剂体系还促进了双烯酮与醛的高度对映选择性反应,这导致形成光学活性的5-羟基-3-氧代酯。
  • 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。
  • Purification and Characterization of A Novel (<i>R</i>)-Hydroxynitrile Lyase from<i>Eriobotrya japonica</i>(Loquat)
    作者:Techawaree UEATRONGCHIT、Ai KAYO、Hidenobu KOMEDA、Yasuhisa ASANO、Aran H-KITTIKUN
    DOI:10.1271/bbb.80023
    日期:2008.6.23
    A hydroxynitrile lyase was isolated and purified to homogeneity from seeds of Eriobotrya japonica (loquat). The final yield, of 36% with 49-fold purification, was obtained by 30–80% (NH4)2SO4 fractionation and column chromatography on DEAE-Toyopearl and Concanavalin A Sepharose 4B, which suggested the presence of a carbohydrate side chain. The purified enzyme was a monomer with a molecular mass of 72 kDa as determined by gel filtration, and 62.3 kDa as determined by SDS-gel electrophoresis. The N-terminal sequence is reported. The enzyme was a flavoprotein containing FAD as a prosthetic group, and it exhibited a K  m of 161 μm and a k  cat⁄K  m of 348 s−1 mm−1 for mandelonitrile. The optimum pH and temperature were pH 5.5 and 40 °C respectively. The enzyme showed excellent stability with regard to pH and temperature. Metal ions were not required for its activity, while activity was significantly inhibited by CuSO4, HgCl2, AgNO3, FeCl3, β-mercaptoethanol, iodoacetic acid, phenylmethylsulfonylfluoride, and diethylpyrocarbonate. The specificity constant (k  cat⁄K  m) of the enzyme was investigated for the first time using various aldehydes as substrates. The enzyme was active toward aromatic and aliphatic aldehydes, and showed a preference for smaller substrates over bulky one.
    从枇杷(Eriobotrya japonica)种子中分离并纯化出一种羟腈裂解酶,使其达到均一性。通过30-80%(NH4)2SO4分级分离和DEAE-Toyopearl和Concanavalin A Sepharose 4B柱层析,获得了最终产率为36%、纯化倍数为49倍的酶,这表明存在一个碳水化合物侧链。纯化的酶是一个单体,通过凝胶过滤测定的分子质量为72 kDa,通过SDS-凝胶电泳测定的分子质量为62.3 kDa。报道了N-末端序列。该酶是一种含FAD作为辅基的黄素蛋白,对扁桃腈的Km值为161 μm,kcat/Km值为348 s-1 mm-1。最适pH和温度分别为pH 5.5和40 °C。该酶在pH和温度方面表现出极佳的稳定性。属离子对其活性不是必需的,而CuSO4、HgCl2、AgNO3、FeCl3、β-巯基乙醇碘乙酸、苯甲磺酰二乙基焦碳酸酯对其活性有显著抑制作用。首次使用各种醛作为底物研究了该酶的特异性常数(kcat/Km)。该酶对芳香族和脂肪族醛均具有活性,并且对较小的底物比庞大的底物表现出偏好性。
  • Enantioselective trimethylsilylcyanation of some aldehydes by chiral titanium Schiff's base complexes

    The complexes formed between titanium tetraalkoxide and chiral Schiff's bases make excellent catalysts for enantioselective trimethylsilylcyanation of aldehydes to optically active cyanohydrins in high optical yield.

  • Enantioselective trimethylsilylcyanation of some aldehydes catalyzed by chiral Schiff base-titanium alkoxide complexes
    作者:Masahiko Hayashi、Yasunori Miyamoto、Tetsuya Inoue、Nobuki Oguni
    DOI:10.1021/jo00058a037
    日期:1993.3
    A variety of aldehydes (aromatic, heteroaromatic, alpha,beta-unsaturated, and nonconjugate aliphatic aldehydes) has been trimethylsilylcyanated in highly enantiomeric excess (ee) with a catalyst prepared in situ from titanium tetraisopropoxide [Ti(O-i-Pr)4] and chiral Schiff bases. A remarkable rate enhancement was brought about by the addition of the Schiff base into the titanium alkoxide mediated silylcyanation of aldehydes. The chemical structure of chiral Schiff base-titanium alkoxide complexes is discussed based on their C-13 NMR spectra, field desorption (FD) mass spectra, and molecular weights.
