  • Fused Catechol Ethers from Gold(I)-Catalyzed Intramolecular Reaction of Propargyl Ethers with Acetals
    作者:Kamalkishore Pati、Gabriel dos Passos Gomes、Trevor Harris、Igor V. Alabugin
    DOI:10.1021/acs.orglett.5b03522
    日期:2016.3.4
    Selective gold(I)-catalyzed rearrangement of aromatic methoxypropynyl acetals leads to fused catechol ethers (1,2-dialkoxynapthalenes) in excellent yields. Furthermore, this process extends to the analogous heterocyclic and aliphatic substrates. Alkyne activation triggers nucleophilic addition of the acetal oxygen that leads to an equilibrating mixture of oxonium ions of similar stability. This mixture
    选择性金(I)催化芳族甲氧基丙炔基乙缩醛的重排可以以极好的收率得到稠合的邻苯二酚醚(1,2-二烷氧基萘)。此外,该方法扩展到类似的杂环和脂族底物。炔烃活化触发乙缩醛氧的亲核加成,从而导致具有相似稳定性的平衡的氧鎓离子混合物。该混合物通过高度放热的环化反应“动力学自分选”。1,2-二烷氧基萘的选择性形成源自环状中间体通过甲醇的1,4-消除的化学选择性芳构化。
  • Application of Directed Metallation in Synthesis, Part 2: An Expedient Synthesis of Methoxybenzo[b]thiophenes
    作者:Chandrani Mukherjee、Asish De
    DOI:10.1055/s-2002-19752
    日期:——
    A short, simple and expedient synthesis of substituted benzo[b]thiophenes involving directed ortho lithiation-side-chain deprotonation-cyclisation-reduction is described. This method is a valuable improvement over earliersyntheses of the same class of compounds, both with respect to the number of steps and overall yields.

  • Synthesis of Benzo[2,1-b:3,4-b’]dithiophene-4,5-dione Derivatives
    作者:Kazuhiro Kobayashi、Toshikazu Ogata、Daizo Nakamura、Osamu Morikawa、Hisatoshi Konishi
    DOI:10.3987/com-06-10779
    日期:——
    The 1-trimethylsilylimidazole-mediated thiophene ring formation from 6-acylbenzo[b]thiophene-4,5-diones (3), which. were prepared utilizing photoacylation of benzo[b]thiophene-4,5-dione (1) with aliphatic aldehydes, and ethyl mercaptoacetate, followed by acid hydrolysis and oxidation with cerium(IV) ammonium nitrate (CAN), led to one-pot formation of the 3-substituted ethyl 4,5dioxo-4,5-dihydrobenzo[2,1-b:3,4-b ']dithiophene-2-carboxylates (4) in satisfactory yields.
