  • 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

    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.
  • A new strategy for the synthesis of (+)-vernolepin related compounds: an unusual sulfene elimination leads to the 2-oxa-cis-decalin skeleton
    作者:Alejandro F Barrero、J.Enrique Oltra、Mı́riam Álvarez

    (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
    为(+)合成的新策略- vernolepin(1),(+) - vernodalin(2),和(+) - 8- deoxyvernolepin(3)中,从访问germacrolides(+) - salonitenolide(4)和(+)-木香内酯(5)已开发出来。合成中的关键步骤是从胚芽烯到榄香烯骨架的Cope重排,环氧酯中反式δ-内酯的环化以及不寻常的亚砜消除,这会促进反应级联反应生成2-oxa -顺式-萘烷骨架。
