    Stereoselective synthesis of polyenic alarm pheromones of cephalaspidean molluscs
    摘要:
    The stereospecific thallium-accelerated palladium-catalyzed cross-coupling of I-alkenyl boronic acids and I-alkenyl iodides (the Suzuki reaction) is the key step in an efficient approach to several polyenic pheromones isolated from cephalaspidean opisthobranch molluscs.

  • Synthesis of Cyclic Alkenyl Dimethylsiloxanes from Alkynyl Benzyldimethylsilanes and Application in Polyene Synthesis
    作者:Haraldur G. Gudmundsson、Christian J. Kuper、Damien Cornut、Felix Urbitsch、Bryony L. Elbert、Edward A. Anderson
    DOI:10.1021/acs.joc.9b01664
    日期:2019.11.15
    Cyclic dimethylalkenylsiloxanes, useful motifs for (Z)-selective Hiyama cross-coupling, are accessed from alkynyl benzyldimethylsilanes featuring adjacent allylic or homoallylic oxygen substituents by semihydrogenation/debenzylation/cyclization. While formation of 5- and 6-membered rings can be achieved from the free alcohols using fluoride or silanolate, allylic acetate precursors to 5-membered rings
    环状二甲基链烯基硅氧烷是(Z)-选择性Hiyama交叉偶联的有用基序,可通过半氢化/脱苄基/环化作用从具有相邻烯丙基或均烯丙基氧取代基的炔基苄基二甲基硅烷中获得。尽管可以使用氟化物或硅烷醇化物从游离醇中形成5元和6元环,但5元环的烯丙基乙酸酯前体显示出不同的活化方式。通过制备多种含(Z)-烯烃的多烯并将其应用于简明的白三烯B3的合成中,证明了这些化合物的实用性。
  • A Modular, Enantioselective Synthesis of Resolvins D3, E1, and Hybrids
    作者:Felix Urbitsch、Bryony L. Elbert、Josep Llaveria、Penelope E. Streatfeild、Edward A. Anderson

    日期:2020.2.21
    Here, we report a convergent and flexible strategy to prepare these natural products using Hiyama-Denmark coupling of five- and six-membered cyclic alkenylsiloxanes to connect three resolvin fragments, and control the stereochemistry of the natural product (Z)-alkenes. The modular nature of this approach enables the synthesis of novel resolvin hybrids, opening up opportunities for more-extensive investigations
    Resolvins D3和E1是解决炎症的重要信号分子。在这里,我们报告了一种收敛和灵活的策略,使用五元和六元环状烯基硅氧烷的Hiyama-Denmark偶联制备这些天然产物,以连接三个resolvin片段,并控制天然产物(Z)-烯烃的立体化学。这种方法的模块化性质使得能够合成新颖的RESOLVIN杂种,为进行RESOLVIN生物学的更广泛的研究提供了机会。
  • Total Synthesis of the Callipeltoside Aglycon
    作者:Ian Paterson、Robert D. M. Davies、Rodolfo Marquez
    DOI:10.1002/1521-3773(20010202)40:3<603::aid-anie603>3.0.co;2-o

    Following macrolactonization, a Sonogashira coupling leads efficiently from 1 and 2 to the aglycon of the structurally unique cytotoxic macrolide callipeltoside A, isolated in tiny quantities from the lithistid sponge Callipelta sp. Key steps in the preparation of macrolide precursor 1 include a boron-mediated anti-aldol coupling (A) in tandem with Yamamoto's vinylogous aldol reaction (B). TES=triethylsilyl
    大内酯化后,Sonogashira偶联有效地从1和2引到结构独特的细胞毒性大环内酯卡比替洛糖苷A的糖苷配基,该糖苷从少量的自噬组织海绵Callipelta sp。中分离出来。制备大环内酯前体1的关键步骤包括与山本的乙烯基醛醇缩醛反应(B)串联的硼介导的抗醛醇缩合偶联(A)。TES =三乙基甲硅烷基。

  • Synthesis and biological activity of α,β,γ,δ-unsaturated aldehydes from diatoms
    作者:Sven Adolph、Serge A Poulet、Georg Pohnert

    α,β,γ,δ-Unsaturated aldehydes have gained increasing attention since 2,4-decadienal and 2,4,7-decatrienal were isolated from the diatom Thalassiosira rotula and characterized as cell antiproliferative metabolites. Structurally related α,β,γ,δ-unsaturated aldehydes were found in this alga as well as in other diatom species. We present a short and universal synthesis of this compound class along with
    自从旋转硅藻Thalassiosira rotula分离出2,4-癸二烯醛和2,4,7-十二碳烯醛并表征其为细胞抗增殖代谢产物以来,α,β,γ,δ-不饱和醛类受到越来越多的关注。在该藻类以及其他硅藻物种中发现了与结构相关的α,β,γ,δ-不饱和醛。我们提供了该化合物类别的简短而通用的合成方法,以及对抑制海胆卵裂的潜力的结构活性研究。Pd 0-或Co II介导的5-碘-戊-2,4-二烯醛与有机锌的交叉偶联可从该通用前体快速灵活地合成许多醛。前体双键系统的立体化学在偶联过程中得以保留。生物测定法表明,与短链脂族同系物和共轭双系统的ω-氧代酸相比,侧链的极性对于抗增殖活性非常重要,其中2,4-癸二烯是最活泼的化合物。相反,双键几何形状对生物活性没有影响。α,β-不饱和2 E-癸烯也具有很高的活性,而在类似链长的饱和醛的情况下,活性降低。1-癸醇,2-癸酮和癸酸没有活性。
