    Total synthesis of quebecol
    摘要:
    We report here the total synthesis of quebecol, a new polyphenolic compound with potential applications recently isolated from maple syrup and produced during the condensation of the tree acer saccharum's sap. The synthetic approach we developed involves, as key steps, the formation of a dibromoalkene from an alpha-ketoester precursor followed by a double Suzuki-Miyaura reaction to unite the three aromatic rings of the target compound on a tetrasubstituted olefin precursor. Our methodology is an efficient pathway to the target compound and leads the way for future analogs. (C) 2013 Elsevier Ltd. All rights reserved.

    We report here the synthesis of isoquebecol, an unprecedented constitutional isomer of quebecol, a polyphenolic compound discovered in maple syrup. The methodology used to prepare isoquebecol involves, as key steps, the formation of a dibromoalkene from an α-ketoester precursor, followed by a double Suzuki-Miyaura reaction. The anti-inflammatory activity of isoquebecol was studied on macrophage cells
    我们在这里报告了异方苯酚的合成,异方苯酚是枫糖浆中发现的多酚化合物quebecol的前所未有的结构异构体。制备异白酚的方法学涉及关键步骤,即由α-酮酸酯前体形成二溴代烯烃,然后进行Suzuki-Miyaura双反应。通过监测其抑制LPS诱导的IL-6分泌的能力,研究了异黄柏对巨噬细胞的抗炎活性。结果表明,这种新化合物具有比其天然异构体更高的生物活性。这项研究中还制备了quebecol,异quebecol和模型类似物2,3,3-三苯丙醇的前体和衍生物。

    The cross‐coupling study of gem‐dibromoesters with triarylbismuths furnished a variety of multi‐functional trisubstituted acrylates embedded with aryl, alkene and alkyne scaffolds in high yields under palladium catalysis. Further, the established method was applied in the step‐economic and convergent synthesis of quebecol natural product in good yield.

Our approach requires the preparation of a gem-dibromoalkene precursor from an α-keto ester, followed by the installation of two aryl groups by Suzuki–Miyaura coupling reactions on the two C–Br bonds. Many 2,3,3-triarylacrylic acid esters with one, two, or three different aryl groups were obtained with complete
