  Stereoselective hydrolysis of nitriles and amides under mild conditions using a whole cell catalyst

  摘要：

  An immobilised whole cell Rhodococcus sp. (SP 361) has been shown to be an effective catalyst for the stereoselective hydrolysis of both racemic and prochiral nitrile containing compounds. 2-Alkyl-arylacetonitriles 6a-8a were hydrolysed to (S)-acids and (R)-amides whereas the closely related substrate 9a gave the (R)-acid. A series of prochiral dinitriles 10a-13a were hydrolysed to the corresponding (S)-acids with e.e.'s 22-84%. Models to account for the stereoselectivity of the enzymic hydrolyses have been proposed.

  烯还原酶在水性介质和两相离子液体-水系统中催化（R）-2-芳基丙烯腈的对映选择性合成

  摘要：

  烯还原酶催化的α-亚甲基腈衍生物的对映选择性还原可提供相应的（R）-2-芳基丙腈，并具有较高的转化率。可在水性介质中（与有机助溶剂或通过将底物装载到疏水性树脂上）或在双相离子液体-水系统中研究反应。发现将离子液体与分离的烯还原酶一起使用可改善后处理和底物回收方法。最终手性腈衍生物的合成操作表明如何利用这种生物催化方法制备各种手性化合物。

  日期：2001.12

  The enantioselective hydrolysis of 17 racemic α-substituted arylacetonitriles by Rhodococcus sp. CGMCC 0497 is described. The corresponding (R)-amides and (S)-acids were obtained with excellent enantiomeric excess in most cases. The effect of steric and electronic factors on the outcome of the reactions are discussed here. The results prove that nitrile-converting enzymes are efficient tools for the

  The enantioselective reduction of α‐methylene nitrile derivatives catalysed by ene‐reductases affords the corresponding (R)‐2‐arylpropanenitriles with high conversion values. The reaction is investigated either in aqueous medium (with an organic cosolvent or by loading the substrate onto hydrophobic resins) or in a biphasic ionic liquid–water system. The use of ionic liquids, herein with isolated ene‐reductases
