  • Heteroaromatic Trapping of Tricyclic 2-Oxidocyclopentenyl Cations: A Surprisingly Efficient Example of Intermolecular Interrupted Nazarov Reaction
    作者:Frederick G. West、Curtis J. Rieder、Ryan J. Fradette
    DOI:10.3987/com-09-s(s)132
    日期:——
    Bis(cycloalkenyl) ketones 2a and 2f underwent Nazarov cyclization and intermolecular trapping by electrophilic aromatic substitution with furans, thiophenes, pyrroles, indoles and dimethoxybenzene. Only the cis-anti-cis diastereomer was isolated with dicyclopentenyl ketone 2a, whereas a mixture of diastereomers was seen with 2f (albeit with complete regioselectivity). Comparable interrupted Nazarov trapping was not seen with acyclic dienones 2b-e, indicating the possible involvement of conformation effects in the polycyclic intermediates derived from 2a and 2f.
  • Homologous Mukaiyama Reactions via Trapping of the Nazarov Intermediate with Silyloxyalkenes
    作者:Yen-Ku Wu、Robert McDonald、F. G. West
    DOI:10.1021/ol201125h
    日期:2011.7.15
    Treatment of 1,4-pentadien-3-ones and silyloxyalkenes with BF3 center dot OEt2 at room temperature or lower initiates a domino process consisting of sequential 4 pi electrocyclization and capture of the resulting cyclopentenyl cation by the electron-rich trap. The overall process furnishes 1,4-dicarbonyl products containing highly substituted cyclopentanones in good yields and with the establishment of up to five new stereocenters.

    [reaction: see text] Simple 1,4-dien-3-ones and 1,3-dienes react in the presence of BF(3).OEt(2) via a domino Nazarov electrocyclization/intermolecular [4 + 3]-cycloaddition sequence to furnish keto-bridged cyclooctenes in good yield. Most cases showed high diastereofacial selectivity and/or endo/exo selectivity, and surprising levels of regioselectivity were observed when isoprene was used as the
