(R)-4-Phenyl-2-butanol 2a, which is used as a precursor to antihypertensive agents and spasmolytics (anti-epileptic agents), was obtained using L kefiri P2 in 99% conversion and 91% enantiomeric excess (ee). Moreover, bioreduction of 2-methyl-1-phenylpropan-1-one substrate 8, containing a branched alkyl chain and difficult to asymmetric reduction with chemical catalysts as an enantioselective, to (R)-2-methyl-1-phenylpropan-1-ol
摘要 酮的生物催化不对称还原是生产手性甲醇的有效方法。该研究表明,不同酮类 ( 1-8 ) 以低至高选择性 (0->99%)选择性生物还原为它们各自的 ( R )-醇 ( 1a-8a ),产率良好 (11-96%)。在这项工作中,研究了开菲尔乳杆菌P2的全细胞催化的各种前手性酮的对映选择性还原。( R )-4-Phenyl-2-butanol 2a,用作抗高血压药和解痉药(抗癫痫药)的前体,使用L kefiri获得P2 转化率为 99%,对映体过量 (ee) 为 91%。此外,2-methyl-1-phenylpropan-1-one 底物8(含有支链烷基链且难以用化学催化剂作为对映选择性的不对称还原)生物还原为 ( R )-2-methyl-1-phenylpropan-1-对映体纯形式的ol (8a)以优异的产率(96%)进行。进行克级生产,以96%的收率获得9.70g对映体纯形式的(
