  Enantiomerically enriched bifunctional sec-alcohols prepared by Candida antarctica lipase B catalysis. Evidence of non-steric interactions

  摘要：

  Transesterification catalysed by Candida antarctica lipase B was used for the preparation of enantiomerically enriched bifunctional sec-alcohols. The enantiomeric ratio, E, for 3-butyn-2-ol was increased from 1.3 to over 500 by adding an easily removable protecting group. Kinetic resolution of bromohydrins and chlorohydrins bearing a halogen on the large substituent showed high enantioselectivity (E>80). On the other hand, halohydrins with the halogen on the medium group showed low E. Large differences in enantioselectivity were found by substituting the halogen atom of 1-halo-2-alkanols by a methyl group. These differences corresponded to more than 2 kcal mol(-1) and were ascribed to non-steric interactions. (C) 1997 Elsevier Science Ltd. All rights reserved.

  one-pot reaction sequence starting from prochiral α-chloroketones leading to enantiopure β-azidoalcohols and β-hydroxynitriles is described. Asymmetric bioreduction of α-chloroketones by hydrogen transfer catalysed by an alcohol dehydrogenase (ADH) established the stereogenic centre in the first step to furnish enantiopure chlorohydrin intermediates. Subsequent biocatalysed ring closure to the epoxide

  A novel one-pot, two-step, two-enzyme cascade is described. Pro-chiral α-chloro ketones are stereoselectively reduced to the corresponding halohydrins as an intermediate by a biocatalytic hydrogen transfer process. The intermediate is transformed to the corresponding epoxide by a non-enantioselective halohydrin dehalogenase. Thus, by combining a Prelog- or anti-Prelog alcohol dehydrogenase with a non-selective

  描述了一种新颖的一锅两步两酶级联反应。通过生物催化氢转移过程，将手性前体α-氯酮立体选择性地还原为相应的卤代醇作为中间体。中间体通过非对映选择性卤代醇脱卤酶转化为相应的环氧化物。因此，通过将Prelog-或抗Prelog醇脱氢酶与非选择性卤代醇脱卤素酶组合，可获得对映纯（R）-和（S）-环氧化物。

  The bakers’ yeast reduction of a series of 2-oxoalkyl arenecarboxylates [R(C=O)CH2O(C=O)C6H4-p-X] (1a–f) (R = CH3 to n-C6H13; X = H) and the phenyl-modified derivatives (1g–l) (R = n-C5H11, X = OH, CH3, F, Cl, Br, or I) as well as 1-chloro-2-alkanones R(C=O)CH2Cl (6a–f) (R = CH3 to n-C6H13) were systematically investigated. The substrate specificities, configuration and %ee of the reduction products were found to be highly dependent on the length of the alkyl group (R) and the α substituent. Thus, the benzoates 1a–f gave optically active 2-hydroxyalkyl benzoates (2a–f) (R, configuration, %ee) (a: CH3, S, 99; b: C2H5, S, 98; c: C3H7, S, 26; d: n-C4H9, R, 55; e: n-C5H11, S, 15; f: n-C6H13, S, 63) in 11–91% yields. Among the modification experiments of the phenyl group, 1g–l, the p-iodo substituent markedly increased the ee from 15 to 71%, although the yield was rather lowered (22% yield). The reduction of α-chloro ketones 6a–f also gave optically active 1-chloro-2-alkanols (7a–f) [(R, configuration, %ee) (a: CH3, S, 83; b: C2H5, S, 54; c: C3H7, R, 49; d: n-C4H9, R, 80; e, n-C5H11, R, 65; f, n-C6H13, R, 41)] in 16–69% yields.

  对一系列2-氧代烷基苯甲酸酯[R(C=O)CH2O(C=O)C6H4-p-X]（1a-f）（R = CH3 至 n-C6H13；X = H）和苯基修饰衍生物（1g-l）（R = n-C5H11，X = OH、CH3、F、Cl、Br 或 I）以及1-氯-2-烷酮R(C=O)CH2Cl（6a-f）（R = CH3 至 n-C6H13）的面包酵母还原进行了系统研究。发现底物特异性、构型和还原产物的%ee高度依赖于烷基链的长度（R）和α取代基。因此，苯甲酸酯1a-f得到了光学活性的2-羟基烷基苯甲酸酯（2a-f）（R，构型，%ee）（a：CH3，S，99；b：C2H5，S，98；c：C3H7，S，26；d：n-C4H9，R，55；e：n-C5H11，S，15；f：n-C6H13，S，63），产率为11-91%。在苯基修饰实验中，1g-l，碘取代基显著提高了ee值，从15%增加到71%，尽管产率明显下降（产率22%）。α-氯代酮6a-f的还原也得到了光学活性的1-氯-2-烷醇（7a-f）[（R，构型，%ee）（a：CH3，S，83；b：C2H5，S，54；c：C3H7，R，49；d：n-C4H9，R，80；e，n-C5H11，R，65；f，n-C6H13，R，41）]，产率为16-69%。

  3-Alkenyl and heteroaryl chloroalcohols have been obtained in excellent enantiomeric excess (>99%) by enzymatic kinetic resolution using the haloalcohol dehalogenase HheC. Yields were close to the theoretical maximum for all substrates employed. Furthermore, the applicability of this methodology on multigram scale has been established.

  通过使用卤醇脱卤酶HheC进行酶促动力学拆分，成功获得了具有优异对映体过剩（>99%）的3-烯基和杂芳基氯醇。所有使用底物的产率均接近理论最大值。此外，该方法在大规模多克重应用中的适用性也得到了验证。

  An iridium catalysed oxidation was coupled concurrently to an asymmetric biocatalytic reduction in one-pot; thus it was shown for the first time that iridium- and alcohol dehydrogenase-catalysed redox reactions are compatible. As a model system racemic chlorohydrins were transformed to enantioenriched chlorohydrins via an oxidation-asymmetric reduction sequence.
