  Synthesis of marine oxylipin topsentolide A1 and its stereoisomers, and determination of the absolute configuration of the natural product

  摘要：

  Four possible stereoisomers of topsentolide A(1), a cytotoxic oxylipin against human solid tumor cell lines, were efficiently synthesized in a stereoselective manner in order to determine the stereochemistry of natural product. The absolute configuration of topsentolide A(1) was determined to be 8R,11R,12S by comparing NMR spectra and specific rotations of the synthetic isomers and the natural product. Cytotoxicity of the synthetic isomers was also examined. (C) 2015 Elsevier Ltd. All rights reserved.

• Synthesis of Marine Oxylipins Constanolactones C and D
  作者：Jörg Pietruszka、Anja Rieche、Niklas Schöne

  DOI：10.1055/s-2007-986647

  日期：2007.10

  After providing the marine oxylipins constanolactones A and B, the next two members of this family were synthesized for the first time. Key to the success was a highly enantioselective and Z-selective reagent-controlled allyl addition (>99%) en route to the aliphatic side chain.

  在提供海洋oxylipins constanolactones A和B之后，该家族的下两个成员首次被合成。成功的关键是高度对映选择性和 Z 选择性试剂控制的烯丙基加成 (>99%) 到脂肪族侧链。

  describe the first total synthesis of 14-A4t-NeuroP in an enantioselective and stereoselective fashion, by means of a new and rapid approach for the installation of the ω chain based on a chemoselective Julia−Kocienski olefination. Furthermore, the construction of the 4,5-cis-disubstituted cyclopentenone moiety characteristic of class A neuroprostanes is achieved in a stereospecific fashion, and suitable

  长期以来，氧化应激与衰老和与年龄有关的病理（例如神经退行性疾病）有关。体内氧化应激的直接作用之一是通过活性氧对膜磷脂的作用形成称为异前列腺素的前列腺素样化合物。由二十二碳六烯酸（C22：6ω3，DHA）形成的异前列腺素的一个特殊亚类，称为神经前列腺素，被认为对神经元氧化应激具有特异性。由于异前列腺素被认为是氧化应激的黄金标准，并且由于神经前列腺素在神经元中对这种状况的特异性及其与阿尔茨海默氏病和帕金森氏病的关系，因此可以预见它们将是这些病理学的合适生物标志物。在这里，我们描述了14-A 4t的第一个全合成-NeuroP以对映选择性和立体选择性的方式，通过一种新的快速方法来安装基于化学选择性Julia-Kocienski烯烃的ω链。此外，以立体特异性方式实现了A类神经前列腺素特征性的4，5-顺式-二取代的环戊烯酮部分的构建，并且已经调整了合适的反应条件以避免不稳定的立体异构中心的差向异构化。

  日期：2010.5

  Two possible stereoisomers of topsentolide A(1), a cytotoxic oxylipin against human solid tumor cell lines, were prepared in order to determine the stereochemistry of natural product. That is, the enantiomer of topsentolide A(1), (85,115,12R)-isomer, and its diastereomer was efficiently synthesized in a stereoselective manner. The stereochemistry of topsentolide A(1) was determined to be 8R,11R,12S by comparing NMR spectra and specific rotations of the synthetic isomers and the natural product. (C) 2010 Elsevier Ltd.
