    Chemoenzymatic approach to optically active phenylglycidates: resolution of bromo- and iodohydrins
    摘要:
    Enantiomerically enriched phenylglycidates, precursors of the taxol C-13 phenylisoserine side chain and diltiazem. were prepared by kinetic resolution of anti-2-bromo-3-hydroxy- and anti-3-hydroxy-2-iodophenylpropanoates to provide enantioriched (2R,3R)- and (2S,3S)-halohydrins. The bulkiness and inflexibility of bromo and iodo groups in halohydrins have made them inaccessible to the active site of most of the lipases utilized for the hydrolysis of their acyloxy derivatives. In a set of 22 hydrolases screened herein, including native as well as commercial enzymes, only Aspergillus niger (Lipase AS, AMANO) could catalyze the hydrolysis with high enantioselectivity (E = 176). The resolved halohydrins easily underwent transformation to the corresponding (2S,3R)- and (2R,3S)phenylglycidates. (C) 26 E'lsevier Ltd. All rights reserved.

    日期:2008.5.1
    and highly efficient method for the rearrangement of bromohydrins mediated by Et2Zn to synthesize carbonyl compounds was described. Various β-bromo alcohols were treated with 0.6 equiv of Et2Zn to form a zinc complex in CH2Cl2 at room temperature for 2 h, followed by 1,2-migration to give the corresponding carbonyl compounds. This remarkable and clean rearrangement is general for acyclic and cyclic bromohydrins
    描述了一种简单高效的方法,用于重排由Et 2 Zn介导的代醇以合成羰基化合物。用0.6当量的Et 2 Zn处理各种β-代醇,在CH 2 Cl 2中形成络合物在室温下反应2小时,然后进行1,2-迁移,得到相应的羰基化合物。对于无环和环状的代醇,这种显着且清洁的重排是普遍的,并且根据起始的代醇的特征,以良好或优异的收率获得了各种环膨胀和收缩的羰基化合物。该反应中有机锌试剂的官能团耐受性将用于有机合成中。还研究了这种重排过程的范围和局限性。
