    Deracemization of 1,2-diol monotosylate derivatives by a combination of enzymatic hydrolysis with the Mitsunobu inversion using polymer-bound triphenylphosphine
    摘要:
    The deracemization of 1,2-diol monotosylate derivatives is achieved by the sequential combination of enzymatic hydrolysis and Mitsunobu inversion using a polymer-bound triphenylphosphine. After the lipase-catalysed hydrolysis of the racemic 2-acetoxyhexyl tosylate, the subsequent Mitsunobu reaction without separation causes an inversion of the resulting (R)-alcohol to give the (S)-enantiomer of the acetate as a single product. In particular, the reaction using the polymer-bound triphenylphosphine also proceeds smoothly, and the product is easily separated by filtration from the polymer-bound reagent and its by-products. This deracemization process is applicable to the preparation of several optically active 1,2-diol monotosylates. (C) 2009 Elsevier Ltd. All rights reserved.

  • Immobilization of lipase from Burkholderia cepacia into calcium carbonate microcapsule and its use for enzymatic reactions in organic and aqueous media

    We disclosed a useful procedure for the immobilization of a lipase from Burkholderia cepacia based on its encapsulation into vaterite calcium carbonate microcapsule. The immobilized enzyme had an adequate activity for the hydrolysis of 4-nitrophenyl acetate, which was preserved over 2 years in storage at 4 degrees C. The enantioselective esterification of (+/-)-1-phenylethanol with vinyl acetate using the immobilized lipase smoothly progressed to afford the corresponding optically active compounds, where the enzyme was easily recovered for reuse. Although the hydrolysis of (+/-)-2-acetoxyhexyl tosylate in aqueous solution was catalyzed by the enzyme, the phase transition of calcium carbonate from vaterite to poorly porous calcite during the reaction prevented the access of the reactant to the active site of the lipase, resulting in the significant decrease of the activity of the recovered enzyme. However, the treatment of the immobilized enzyme with zinc chloride solution inhibited the phase transition under the reaction conditions. The enzyme after the zinc treatment was recyclable for the hydrolysis of the substrate without significant decrease of the reactivity even after the uses in aqueous media. (C) 2014 Elsevier B.V.
