  Enantioselective bioreduction of 2-fluoro-2-alken-1-ols mediated by Saccharomyces cerevisiae

  摘要：

  Biocatalytic reduction of 2-fluoro-2-alken-1-ols mediated by Saccharomyces cerevisiae underwent smoothly and yielded (S)-2-fluorinated alkanols with high enantioselectivities. The conversion rate was markedly depending on the configuration of alkene moiety of the substrate, the chain length of alkyl group at beta position of C=C bond, as well as the reaction conditions.

• Efficient Synthesis of Fluoroalkenes via Diethylzinc-Promoted Wittig Reaction

  The synthesis of α-fluoroacrylates and α-bromo-α-fluoroalkenes was achieved in very good yields using aldehydes and ketones, triphenylphosphine, diethylzinc as promoter, and ethyl dibromofluoroacetate or dibromofluoromethane, respectively. A change in the addition sequence was critical in order to obtain exclusively α-fluoroacrylates in good yields.

  α-氟丙烯酸酯和α-溴-α-氟烯烃的合成得到了非常好的产率，使用了醛和酮、三苯基磷、二乙基锌作为促进剂，以及乙基二溴氟乙酸酯或二溴氟甲烷。改变添加顺序对独占性获得α-氟丙烯酸酯的高产率至关重要。

  The title compound 2 can be alkylated with a wide range of alkyl halides and Michael acceptors. Subsequent thermal elimination of phenyl sulfinic acid 3 leads to α-fluoro-α,β-unsaturated ethyl carboxylates 5 and 10, an important class of intermediates for fluorine containing biologically active compounds.

  标题化合物2可以用多种烷基卤化物和迈克尔受体烷基化。随后热消除苯基亚磺酸3会导致α-氟代-α，β-不饱和羧酸乙酯5和10，这是含氟生物活性化合物的重要中间体。

  A efficient methodology allowing the one-pot stereoselective synthesis of alpha-fluoroacrylates, based on the addition of ethyl dibromofluoroacetate to a carbonyl derivative using diethylzinc as organometallic mediator, is described. Two different pathways have been identified depending on the involved carbonyl partner. In the case of aldehydes, an E2-type mechanism has been identified, whereas ketones go through an E1cb-type mechanism.
