  • Introduction of the (−)-Berkelic Acid Side Chain and Assignment of the C-22 Stereochemistry
    作者:Xiaoxing Wu、Jingye Zhou、Barry B. Snider

    日期:2009.8.21
    oxidized and deprotected to complete the synthesis of ()-berkelic acid and ()-22-epi-berkelic acid. This synthesis establishes the absolute stereochemistry and assigns the stereochemistry at C-22. A biosynthetic pathway is proposed that is consistent with the known absolute stereochemistry at the quaternary carbon of spiciferone A, spicifernin, and berkelic acid and provides a simple explanation for
    醛与三甲基甲硅烷基乙烯酮缩醛的 Kiyooka 羟醛缩合反应和由N -Ts-( S )-缬氨酸制备的恶唑硼烷酮得到四种可能的羟醛加合物中的两种,它们被氧化和脱保护以完成 (-)-berkelic 的合成酸和 (-)-22- epi- berkelic 酸。该合成建立了绝对立体化学并将立体化学指定为 C-22。提出了一种生物合成途径,该途径与已知的 spiciferone A、spicifernin 和 berkelic 酸的季碳上的绝对立体化学一致,并为 spicifernin 和 berkelic 酸的 C-18 和 C-19 的不同立体化学提供了简单的解释。
  • Formal Synthesis of Berkelic Acid: A Lesson in α-Alkylation Chemistry
    作者:Michael C. McLeod、Zoe E. Wilson、Margaret A. Brimble
    DOI:10.1021/jo201988m
    日期:2012.1.6
    The full details of our enantioselective formal synthesis of the biologically active natural product berkelic acid are described. The insertion of the C-18 methyl group proved challenging, with three different approaches investigated to install the correct stereochemistry. Our initial Horner–Wadsworth–Emmons/oxa-Michael approach to the berkelic acid core proved unsuccessful upon translation to the
    描述了我们的对映选择性形式合成的生物活性天然产物伯酸的完整细节。C-18甲基的插入被证明具有挑战性,已研究了三种不同的方法来安装正确的立体化学。我们最初对Berkelic酸核心的Horner–Wadsworth–Emmons / oxa-Michael方法在转化为天然产物本身后被证明是不成功的。然而,将甲硅烷基烯醇醚添加至氧鎓离子,然后进行一锅脱苄基化/螺酮基化/热力学平衡程序,得到了作为单一非对映异构体的伯克利酸核心的四环结构。
  • An Enantioselective Formal Synthesis of Berkelic Acid
    作者:Michael C. McLeod、Zoe E. Wilson、Margaret A. Brimble
    DOI:10.1021/ol202265g
    日期:2011.10.7
    An enantioselective formal synthesis of berkelic acid is described. The key step Involves a late-stage silyl enol ether addition to a benzannulated oxonium ion with subsequent spiroketalization leading to construction of the tetracyclic core. Thermodynamically controlled equilibration under acidic conditions affords the desired spiroketal configuration as a single diastereoisomer.
  • A Diastereoselective Formal Synthesis of Berkelic Acid
    作者:Todd A. Wenderski、Maurice A. Marsini、Thomas R. R. Pettus
    DOI:10.1021/ol102652t
    日期:2011.1.7
    A formal synthesis of berkelic acid is reported. The strategy employs the combination of a chiral exocyclic enol ether and an achiral isochromanone to afford the chroman spiroketal core via a base-triggered generation and cycloaddition of an o-quinone methide intermediate. Other key steps include equilibration of the spiroketal, intramolecular benzylic oxidation, and lactone addition/hemiketal reduction;

    AbstractAn extremophilic challenge: Stereospecific condensation of a fully functionalized ketal aldehyde and a 2,6‐dihydroxybenzoic acid is the key step in the synthesis of (−)‐berkelic acid confirming Fürstner's reassignment of the stereochemistry at C18 and C19, establishing the absolute stereochemistry, and tentatively assigning the stereochemistry at C22.magnified image
