  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.

  photoisomerization with sunlight. Hydroperoxide, isolated form Placida dendritica, was synthesized both by singlet oxygenation of cyercene A using Rose Bengal and through the irradiation of cyercene A alone in aerobic solution. The observation that hydroperoxide could be made by singlet oxygenation of cyercene A and that this occurs when cyercene A alone is irradiated supported the hypothesis that gamma-pyrones

  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。

  An efficient approach to the total synthesis of the marine derived polypropionate cyercene A is described. A key feature of the synthesis is the development of methodology for the diastereoselective Wadsworth-Emmons type condensation of a functionalised gamma-pyrone unit. (C) 2004 Elsevier Ltd.
