    An Unusual Domino Claisen−Conia Reaction Producing 3,5-Dispirodihydrofuran-2,4-diones
    摘要:
    Allyl tetronates 3 can be selectively converted either (in acetonitrile) into Claisen-rearranged 3-allyltetronic adds 5 or (in toluene) into novel Claisen-Conia-rearranged 3-(spirocyclopropyl)dihydrofuran-2,4-diones 6, featuring up to three new stereogenic centres. The mechanism and the stereochemistry of this process is discussed and an X-ray crystal structure of one of the two diastereoisomers of (+/-)-6c is presented.

  • Abnormal Claisen rearrangements of tetronates and stereoselective ring opening of intermediate spirocyclopropanes
    作者:Rainer Schobert、Sven Siegfried、Gary Gordon、Daniel Mulholland、Mark Nieuwenhuyzen
    DOI:10.1016/s0040-4039(01)00773-0
    日期:2001.7
    Thermal [2,3]-sigmatropic rearrangements of allyltetronates proceed via 3-(spirocyclopropyl)dihydrofuran-2,4-diones; in some cases these could be isolated and their cyclopropane rings stereoselectively opened with alcohols or water to give 3-(β-syn-alkoxy)tetronic acids. Treatment of a 5,5-disubstituted benzyltetronate with LDA also produced a 3-substituted tetronic acid by an anionic [1,3]-rearrangement
    烯丙基四酸酯的热[2,3]-σ重排通过3-(螺环丙基)二氢呋喃-2,4-二酮进行;在某些情况下,可以将其分离,并用醇或水将其环丙烷环立体选择性地打开,得到3-(β-顺式烷氧基)tetronic酸。用LDA处理5,5-二取代的苄基四乙酸也通过阴离子[1,3]重排产生了3-取代的四氢苯甲酸。
  • 3-Functionalized Tetronic Acids From Domino Rearrangement/Cyclization/Ring-Opening Reactions of Allyl Tetronates

    Allyl tetronates 1 thermally rearrange to stable 3-(spirocyclopropyl)dihydrofuran-2,4-diones 2 (R3 = H, Aryl), which can be ring-opened with O-, N-, S- and C-nucleophiles to give 3-substituted tetronic acids 3−7. Compounds 2 with R3 = Alkyl are not isolable, but are interceptable intermediates in formal [2,3]-sigmatropic rearrangements of allyl tetronates. The vinylogous hexadienyl tetronate 17 undergoes
