    Approach to(R)- and (S)-ketone cyanohydrins using almond and apple meal as the source of (R)-oxynitrilase
    摘要:
    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.

  • Synthesis of Aliphatic and α-Halogenated Ketone Cyanohydrins with the Hydroxynitrile Lyase from <i>Manihot esculenta</i>
    作者:Johannes Diebler、Jan von Langermann、Annett Mell、Martin Hein、Peter Langer、Udo Kragl

    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。

    (13)C NMR, alone or in combination with (1)H NMR, allows the assignment of the absolute configuration of chiral alcohols, amines, carboxylic acids, thiols, cyanohydrins, sec,sec-diols and sec,sec-aminoalcohols, derivatized with appropriate chiral auxiliaries. This extends the assignment possibilities of NMR to fully deuterated and to nonproton containing compounds.
