  Chemoenzymatic synthesis of enantiopure 1-phenyl-2-haloethanols and their esters

  摘要：

  Several secondary haloalcohols have been resolved by esterification catalyzed by lipases A and B from Candida antarctica (CALA and CALB, respectively). Immobilized CALB (Novozym 435) gave better selectivities and faster reaction rates than CALA (Novozyme 735) with all of the substrates. Vinyl butanoate was the favoured acyl donor compared to vinyl acetate due to remarkably faster reactions. The alcohols (R)-2a, (R)-2c and the butanoates (S)-3a-c have been isolated with 98-99% enantiomeric excess (ee) in good yields.

• DMSO-triggered enhancement of enantioselectivity in Novozyme[435]-catalyzed transesterification of chiral 1-phenylethanols

  Dimethyl sulfoxide as cosolvent enhances the enantioselectivity of resolved products up to 100% in the Novozyme[435]-catalyzed transesterification of chiral 1-phenylethanols but not 1-phenyl-2-haloethanols in THF. The reaction does not proceed in lipophilic and water-miscible polar solvents.

  二甲基亚砜作为助溶剂，在Novozyme [435]催化的手性1-苯基乙醇（而非1-苯基-2-卤代乙醇）在THF中的酯交换反应中，可将拆分产物的对映选择性提高至100％。该反应不会在亲脂性和水混溶性极性溶剂中进行。

  Reduction of acetophenones with sodium borohydride in the presence of neutral alumina in hexane followed by enantioselective acylation catalyzed by Pseudomonas cepacia lipase has been achieved in one-pot. Further, immobilized lipase offered a high degree of selectivity with spontaneity. (C) 2002 Elsevier Science Ltd. All rights reserved.
