  • Synthesis of α-hydroxy-β,β-difluoro-γ-ketoesters via [3,3]sigmatropic rearrangements
    作者:Michael J. Broadhurst、Samantha J. Brown、Jonathan M. Percy、Michael E. Prime
    DOI:10.1039/b004766j
    日期:——
    Readily available γ,γ-difluorinated allylic alcohols obtained from trifluoroethanol were esterified efficiently. Exposure to strong base (LDA) afforded the ester enolates, in which chelation both controlled configuration and stabilised against fragmentation, which were trapped as their silyl ketene acetals. Rearrangement occurred to afford base-sensitive acid products. Esterification under mild conditions
    易得的γ,γ-二氟烯丙基醇得自 三氟乙醇被有效地酯化。暴露于强大的基础(LDA)提供了 酯 烯醇盐,其中的螯合物既可控制构型,又能稳定防止碎裂,它们被捕获为甲硅烷基烯酮 缩醛。发生重排,得到碱敏酸产物。在温和的条件下进行酯化,得到可纯化的甲基酯,其中被掩盖的酮已被释放。在α位置带有苄氧基或烯丙氧基的离去物可以脱保护并释放酒类。
  • [3,3]-Sigmatropic Rearrangement Routes to β-Fluoro- and β,β-Difluoro-carbonyl Derivatives.

    Difluoroallylic alcohols prepared in two steps from trifluoroethanol underwent a range of Claisen and related [3,3]-rearrangements in moderate to good yield. In one case, the rearrangement product underwent rapid dehydrofluorination to afford an interesting fluorodienal Monofluoroallylic alcohols rearranged more slowly but resisted dehydrofluorination.
    由三氟乙醇分两步制备的二氟烯丙醇以中等至良好的收率进行了一系列的Claisen和相关的[3,3]重排。在一种情况下,重排产物经历快速的脱氟化氢作用,得到令人感兴趣的氟二烯单氟代烯丙基醇,其重排的速度较慢,但​​抵抗了脱氟化氢作用。
  • Facile [2,3]-rearrangements of difluoroallylic alcohols with CP and CS bond formation

    chlorodiphenylphosphine, to the corresponding sulfoxides and phosphine oxides. In the primary cases, the rearrangement was considerably slower, while in the tertiary cases, SN2′ chlorination reactions competed to a significant extent. Heating the sulfoxide products with triethyl phosphite failed to induce conversion back to the allylic alcohols, consistent with the strong preference of the CF2 centre for

    日期:1995.8
    A new fluorine containing acyl anion equivalent 1,1-difluoro-2-lithio-2-[(methoxyethoxy)methoxy]ethene 12 has been prepared from trifluoroethanol and trapped with a number of electrophiles in good yield. Effective electrophiles included Group(IV) halides and carbonyl compounds. Attempts to alkylate using iodomethane were unsuccessful.

  • [2,3]-Wittig Rearrangements of Difluoroallylic Ethers. A Facile Entry to Highly Functionalized Molecules Containing a CF<sub>2</sub> Group
    作者:Sunita T. Patel、Jonathan M. Percy、Robin D. Wilkes
    DOI:10.1021/jo951516h
    日期:1996.1.1
    Readily prepared primary, secondary, and tertiary difluoroallylic alcohols, derived from commercially available and inexpensive 2,2,2-trifluoroethanol, have been transformed into a range of difluoroallylic methyl ethers containing appropriate carbanion-stabilizing substituents. The [2,3]-Wittig rearrangements of these difluoroallylic ethers have been achieved cleanly, using lithium diisopropylamide in tetrahydrofuran at -30 degrees C, in excellent (secondary ether substrates) to good (primary and tertiary ether substrates) yields. Consequently, the approach allows convenient and rapid access to products containing a mid-chain CF2 group and with a useful level of functionality.
