  • Synthesis of Elemane Bis-Lactones from Santonin – Synthesis of the Reported Structure ofseco-Isoerivanin Pseudo Acid and Formal Synthesis of (+)-8-Deoxyvernolepin
    作者:Gonzalo Blay、Luz Cardona、Begoña García、Luisa Lahoz、José R. Pedro
    DOI:10.1002/1099-0690(200006)2000:11<2145::aid-ejoc2145>3.0.co;2-n
    日期:2000.6
    The synthesis of the reported structure for seco-isoerivanin pseudo acid (1) and of an elemane bis-lactone 5 from santonin (4) through a common vinylic precursor 12 is described. Compound 5 is a known intermediate in a previous synthesis of the antitumor compound (+)-8-deoxyvernolepin (3). The vinyl group of 12 underwent a regio- and diastereoselective anti addition of an external electrophile and

  • A new strategy for the synthesis of (+)-vernolepin related compounds: an unusual sulfene elimination leads to the 2-oxa-cis-decalin skeleton

    (2), and (+)-8-deoxyvernolepin (3), from the accessible germacrolides (+)-salonitenolide (4) and (+)-costunolide (5), has been developed. The key steps in the synthesis are a Cope rearrangement from the germacradiene to the elemadiene skeleton, the cyclization of a trans-fused δ-lactone from an epoxy ester, and an unusual sulfene elimination, which promotes a reaction cascade leading to the 2-oxa-cis-decalin

  • Synthesis of (+)-8-Deoxyvernolepin and Its 11,13-Dihydroderivative. A Novel Reaction Initiated by Sulfene Elimination Leads to the 2-Oxa-<i>cis</i>-decalin Skeleton
    作者:Alejandro F. Barrero、J. Enrique Oltra、Míriam Álvarez、Antonio Rosales
    DOI:10.1021/jo0256538
    日期:2002.8.1
    The title compounds are interesting candidates for antifungal screening. This paper describes the enantiospecific synthesis of these compounds starting from (+)-costunolide isolated from a commercially available extract. We used two novel reactions as key synthetic steps in this work: the acid-induced cyclization of an delta,epsilon-epoxy ester, which stereoselectively gave a hydroxymethyl-substituted delta-lactone, with the hydroxyalkyl group in the desired beta-equatorial disposition, and a reaction cascade, initiated by a base-promoted sulfene elimination, which led to a 10-oxiranyl-2-oxa-cis-decalin from the mesylate of a trans-fused delta-lactone. We also found that the reaction between selenium dioxide and the 1,5-diene system of elemanolides gave selenadecalins analogous to natural eudesmanolides. Our results prove that the synthetic strategy employed, on the basis of biomimetic concepts, is a useful procedure for the enantiospecific preparation of (+)-vernolepin-related compounds from accessible germacrolides.
