  Ionic liquids for enhancing the enantioselectivity of isolated BVMO-catalysed oxidations

  摘要：

  本研究首次报道了在离子液体存在下使用分离的耐热贝耶尔-维利格单氧合酶（苯丙酮单氧合酶，PAMO）的情况。研究了不同离子液体存在下，PAMO作为氧化酶的稳定性、活性和选择性。结果显示，添加某些特定离子液体，如Ammoeng™ 102和[bmim]MeSO4，可以显著提高消旋苯甲酮氧化反应的E值。此外，离子液体的使用提高了进行贝耶尔-维利格氧化反应的最佳底物浓度，从而扩大了PAMO在合成应用中的生物催化范围。

  fluorescens ACB was employed in the presence of a weak anion exchange resin to perform dynamic kinetic resolutions of racemic benzyl ketones with high conversions and good optical purities. Different parameters that affect to the efficiency of the enzymatic Baeyer–Villiger oxidation and racemisation were analyzed in order to optimize the activity and selectivity of the biocatalytic system.

  The application of three BVMOs for the enantioselective oxidation of 3-phenylbutan-2-ones with different substituents in the aromatic moiety is described. By choosing the appropriate biocatalyst and substrate combination, chiral ketones and esters can be obtained with excellent enantiopurities. This methodology could also be applied to the resolution of racemic alpha-alkyl benzylketones with longer alkyl chains as well as with two substituted alpha-substituted benzylacetones. A kinetic analysis revealed that the BVMOs studied effectively convert all tested compounds showing that the enzymes are tolerant towards the substrate structure while being highly enantioselective. These properties render BVMOs as valuable biocatalysts for the preparation of compounds with high interest in organic synthesis. (C) 2009 Elsevier Ltd. All rights reserved.

  A method that manufacturers an optically active carboxylic acid ester at high yield and high enantioselectivity is provided. An optically active carboxylic acid ester is manufactured at high yield and high enantioselectivity by reacting a racemic carboxylic acid and a specific alcohol or phenol derivatives in a polar solvent having a dipole moment of 3.0 or higher in the presence of an acid anhydride and an asymmetric catalyst, esterifying one enantiomer of the racemic carboxylic acid at high selectivity, and increasing the amount of esterified carboxylic acid by racemizing the optically active carboxylic acid which is the other enantiomer not used in esterification.

  The present study describes the first-time usage of an isolated thermostable Baeyer–Villiger monooxygenase (phenylacetone monooxygenase, PAMO) in the presence of ionic liquids. The stability, activity and selectivity of PAMO as an oxidative enzyme in the presence of different ionic liquids were studied. This revealed that the addition of some specific ionic liquids, such Ammoeng™ 102 and [bmim]MeSO4, can significantly enhance the E-value in the oxidation of racemic benzylketones. Moreover, the use of ionic liquids increases the optimal substrate concentration for performing Baeyer–Villiger oxidation, thereby extending the biocatalytic repertoire of PAMO for synthetic applications.
