    Synthesis of Furanophane Derivatives through [8+2]-Cycloaddition of Dienylisobenzofurans and Alkynes
    摘要:
    The coupling of various dienylisobenzofurans with dimethyl acetylenedicarboxylate (DMAD) has been examined. In most cases, this reaction proceeds via [8+2]-cycloaddition to afford furan-bridged decatetraene ring systems. The major competing reaction pathway is [4+2]-cycloaddition between DMAD and the isobenzofuran nucleus. Isobenzofuran intermediates were generated using either a chromium carbene-based method or an acid-catalyzed method.

  • Mechanistic Twist of the [8+2] Cycloadditions of Dienylisobenzofurans and Dimethyl Acetylenedicarboxylate:  Stepwise [8+2] versus [4+2]/[1,5]-Vinyl Shift Mechanisms Revealed through a Theoretical and Experimental Study

    diene moieties of dienylisobenzofurans, the [8+2] reaction occurs through an alternative mechanism involving a [4+2] reaction between the furan moiety of the tetraene and DMAD, followed by a [1,5]-vinyl shift. This computationally predicted novel mechanism was supported experimentally.
