  • Bargellini condensation of coumarins. Expeditious route to o-carboxyvinylphenoxyisobutyric acids and application to the synthesis of sesquiterpenes helianane, heliannuol A and heliannuol C
    作者:Bidyut Biswas、Prabir K. Sen、Ramanathapuram V. Venkateswaran
    DOI:10.1016/j.tet.2007.09.006
    日期:2007.11
    The direct Bargellini condensation of coumarins involving reaction with chloroform and acetone in the presence of aqueous sodium hydroxide furnished o-carboxyvinylphenoxyisobutyric acids in good yields. The utility of this new useful protocol was demonstrated by the transformation of the three diesters 9b, 9f and 9g to the sesquiterpenes helianane 4, heliannuol A 2 and heliannuol C 3, respectively
    香豆素的Bargellini直接缩合反应涉及在氢氧化钠水溶液存在下与氯仿和丙酮反应,从而以良好的收率提供了邻羧基羧乙烯基苯氧基异丁酸。通过将三个二酯9b,9f和9g分别转化为倍半萜烯helaneane 4,heliannuol A 2和heliannuol C 3,证明了该新有用方案的实用性。

    由炔丙基醚-Co 2 (CO) 6配合物产生的 γ-羰基阳离子进行分子内尼古拉斯反应,以良好的收率得到 dehydrobenzoxacin-3-one-Co 2 (CO) 6配合物。还原解络和随后的操作允许合成 (±)-heliannuol K 甲基醚和 (±)-heliannuol K、(±)-heliannuol A 和 (-)-heliannuol L 的正式合成。
  • Synthesis of heliannuols A and K, allelochemicals from cultivar sunflowers and the marine metabolite helianane, unusual sesquiterpenes containing a benzoxocane ring system
    作者:Subrata Ghosh、Kazi Tuhina、Dipal R. Bhowmik、Ramanathapuram V. Venkateswaran
    DOI:10.1016/j.tet.2006.11.014
    日期:2007.1
    Synthesis of the allelochemicals heliannuols A and K, and the sesquiterpene helianane is described. A regioselective cleavage of a benzo-fused oxabicyclo(5.1.0)octane system under hydrogenation as well as radical induced condition was developed to generate the basic benzoxocane ring system of these unusual sesquiterpenes.
    描述了化感物质Heliannuols A和K,以及倍半萜烯Helianane的合成。苯并稠合的氧杂双环(5.1.0)辛烷体系在氢化以及自由基诱导条件下的区域选择性裂解被开发以生成这些不寻常的倍半萜的碱性苯并oc烷环体系。
  • Strategies for the Total Asymmetric Synthesis of Heliannuols K and L: Scope and Limitations
    作者:Frédéric Lecornué、Renée Paugam、Jean Ollivier
    DOI:10.1002/ejoc.200400908
    日期:2005.6
    syntheses of certain compounds in racemic form seem accessible, however, improvements through new strategies are still required for the total asymmetric synthesis. This article describes the first synthesis of enantiomerically enriched OMe-heliannuol K and the first stereo- and enantioselective synthesis of heliannuol L, and new approaches and studies of their limitations in the preparation of these
    带有末端双键的氧杂酯的 Kulinkovich 反应通过分子内环化得到环丙醇。这些可以进行 Saegusa 氧化以提供 β-氯-氧杂环烷酮,然后可以脱卤化氢为氧杂环烯酮。通过明智地选择起始酯,可以获得具有倍半萜烯基本骨架的各种芳基稠合苯并氧杂环酮,例如向日葵醇。尽管外消旋形式的某些化合物的合成似乎是可行的,但是,对于全不对称合成仍然需要通过新策略进行改进。本文描述了对映体富集的 OMe-heliannuol K 的首次合成和 heliannuol L 的首次立体选择性和对映选择性合成,并详细介绍了它们在制备这些产品中的局限性的新方法和研究。(© Wiley-VCH Verlag GmbH & Co.
