    Total synthesis of cyercene A and the biomimetic synthesis of (±)-9,10-deoxytridachione and (±)-ocellapyrone A
    摘要:
    This paper summarises our detailed study towards the biomimetic synthesis of the complex polypropionate derived natural product (+/-)-9,10-deoxytridachione. A previous study based on the elaboration of functionalised gamma-pyrones allowed us to synthesise cyercene A. The same efficient methodology has been applied for the elaboration of a more complex fully conjugated gamma-pyrone polyene. Our approach centred on a key tandem Suzuki-coupling/electrocyclisation reaction, which supports a possible biosynthetic pathway for this class of natural products. A related compound was obtained during our studies, which we identified as the correct structure of ocellapyrone A. (C) 2007 Published by Elsevier Ltd.

    Sacoglossan聚丙烯酸酯中的光化学关系。
    摘要:
    合成了并茂A,并通过在阳光下的光致异构化将其转化为环戊烯A和异环庚烯A。氢过氧化物,是从Placida dendritica中分离出来的,它是通过使用玫瑰红(Bose Bengal)对cA进行单线氧化和通过在有氧溶液中单独照射cA来合成的。氢的过氧化物可以通过by A的单线态氧合而产生,并且仅在照射yer C时会发生这种现象,这支持了γ-吡喃酮可以充当三重态敏化剂的假设。这是通过使用并列烯A和模型γ-吡喃酮来敏化正丁基硫醚的光氧化作用而证实的。讨论了这些观察结果对Sacoglossan聚丙烯酸酯的生物合成意义。

  • A Short Total Synthesis of Aureothin and <i>N</i>-Acetylaureothamine

    The total synthesis of the nitrophenyl pyrones, (+/-)-aureothin and (+/-)-N-acetylaureothamine, starting from known 2-ethyl-6-methoxy-3,5-dimethyl-4H-pyran-4-one are described. The key steps involved in the synthesis are the construction of the tetrahydrofuran motif using a palladium-catalyzed cycloaddition and the ruthenium-catalyzed cross-metathesis reaction of an alkenyl boronic ester.

    of diverse natural products with complex core structures such as 9,10-deoxytridachione, photodeoxytridachione and ocellapyrone A are derived in nature from a linear and conformationally strained all-(E) tetraene−pyrone precursor. We therefore synthesized such a precursor and investigated its biomimetic transformation under a variety of reaction conditions, both to the above natural products as well as
    我们的仿生假说提出,具有复杂核心结构的多种天然产物家族,例如9,10-脱氧三达酮,光脱氧三达酮和ocellapyrone A本质上是从线性和构象应变的全(E)四烯-吡喃酮前体衍生而来的。因此,我们合成了这种前体,并研究了其在多种反应条件下的仿生转化,转化为上述天然产物以及我们认为是“尚待发现”的天然产物的各种异构体。我们还在本文中报道了天然产物iso-9,10-脱氧三丁酮的首次合成。
