  • 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.

  • Application of directed metalation in synthesis. Part 8: Interesting example of chemoselectivity in the synthesis of thioaurones and hydroxy ketones and a novel anionic ortho-Fries rearrangement used as a tool in the synthesis of thienopyranones and thiafluorenones
    作者:Tarun Kanti Pradhan、Asish De、Jacques Mortier
    DOI:10.1016/j.tet.2005.07.050
    日期:2005.9
    Chemoselective synthesis of thioaurones or 3-hydroxy benzo[b]thiophen-2-aryl ketones, 1-hydroxy naphtho[2,1-b]thiophen-2aryl ketones and chalcones from N,N-diethyl-ortho-methyl sulfanyl aryl amides were described. (Benzo[b]thiophen-2-yl) alkylates and (naphtho[2, 1-b]thiophen-2-yl) alkylates undergo a novel anionic ortho-Fries rearrangement leading to (3-hydroxy benzo[b]thiophen-2-yl) and (1-hydroxy naphtho[2, 1 -b]thiophen-2-yl) alkyl ketones. The hydroxy ketones were used as intermediates in the synthesis of wide range of benzothienopyranones and thiafluorenones. (c) 2005 Elsevier Ltd. All rights reserved.
