  Efficient access to fluorinated homoallylic alcohols through an indium promoted fluoroallylation reaction

  摘要：

  Herein, an efficient access to fluorinated homoallylic alcohol is reported. The fluorinated alcohols were obtained in good to excellent yield using indium and halo-fluorinated allylic derivatives. The developed methodology using gamma-substituted halo-fluorinated allylic derivatives gave the corresponding alpha-substituted fluorinated homoallylic alcohol in good yields and good diastereoselectivities up to 86:14.

  serves as an effective promoter for the room-temperature stereoselective synthesis of α,β-unsaturated esters, fluorides, and nitriles from a wide array of aromatic, aliphatic, heterocyclic, and cyclic aldehydes and ketones, using a range of Wadsworth−Emmons (WE) phosphonates. Among the analogues of 1c [R = Me (1a), i-Pr (1b), Bn (1d)], 1a and 1b performed well, although longer reaction times were involved

  双环三氨基膦P（RNCH 2 CH 2）3 N（R = i -Bu，1c）可作为室温下立体选择性合成α，β-不饱和酯，氟化物和腈的有效促进剂芳香族，脂肪族，杂环和环状醛和酮，使用一系列Wadsworth-Emmons（WE）膦酸酯。在1c [R = Me（1a），i -Pr（1b），Bn（1d）]的类似物中，1a和1b表现良好，尽管涉及的反应时间更长，而1d导致的收率低于1c。氰基，氯，溴，甲氧基，氨基，酯和硝基等官能团的耐受性很好。我们能够分离和表征（通过X射线；见上文）由2b和1c形成的反应性WE中间体。

  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.

  日期：——

  An exceptionally stereoselective and general synthesis of (Z)-α-haloacrylates, ready to undergo various synthetic transformations, has been demonstrated from α-haloacetates and aldehydes in a one-pot manner via the titanium-enolate based asymmetric aldol condensation. Besides being an expedient synthetic procedure, the ready availability of diverse α-haloacetates, exceptional stereoselectivity, and high yields make the process a versatile transformation in organic synthesis. The potential of this method in up-scaling operations has been illustrated.
