  • Synthesis of vulpinic and pulvinic acids from tetronic acid
    作者:Yann Bourdreux、Ewen Bodio、Catherine Willis、Célia Billaud、Thierry Le Gall、Charles Mioskowski
    DOI:10.1016/j.tet.2008.06.058
    日期:2008.9
    A common precursor, tetronic acid, was used in the synthesis of several vulpinic acids and pulvinic acids, which are pigments found in several lichens and mushrooms. The key features of this method are a two-step alkylidenation of benzyl tetronate and a Suzuki–Miyaura cross-coupling. The synthesis of several natural products, vulpinic acid, pinastric acid, xerocomic acid is described.

  • Convergent Total Synthesis of Lamellarins and Their Congeners
    作者:Daiki Morikawa、Kazuki Morii、Yuto Yasuda、Atsunori Mori、Kentaro Okano
    DOI:10.1021/acs.joc.0c00998
    日期:2020.7.2
    A convergent total synthesis of lamellarins S and Z is described. The synthesis features a halogen dance of an easily accessible α,β-dibromopyrrole promoted by an ester moiety. The resultant β,β′-dibromopyrrole undergoes a ligand-controlled Suzuki–Miyaura coupling to provide a range of diarylated pyrrole derivatives. The established synthetic method was also applicable to the synthesis of ningalin
    描述了薄片蛋白S和Z的收敛的全合成。该合成的特征是由酯部分促进的易于获得的α,β-二溴吡咯的卤素舞。所得的β,β'-二溴吡咯经过配体控制的Suzuki-Miyaura偶联,可提供一系列二芳基吡咯衍生物。所建立的合成方法也适用于宁纳林B和卢卡醇A和B的合成。
  • Total Synthesis of Lamellarins G, J, L, and Z Using One-Pot Halogen Dance/Negishi Coupling
    作者:Kazuki Morii、Yuto Yasuda、Daiki Morikawa、Atsunori Mori、Kentaro Okano
    DOI:10.1021/acs.joc.1c01505
    日期:2021.10.1
    A bottom-up synthesis of lamellarins G, J, L, and Z was achieved via one-pot halogen dance/Negishi coupling of a lithiated dibromopyrrole derivative. The easily accessible dibromopyrrole bearing an ester moiety underwent halogen dance smoothly at −78 °C within 10 min. The resultant α-pyrrolyllithium was transmetalated to the corresponding organozinc species, which was then coupled with an aryl iodide
    层状蛋白 G、J、L 和 Z 的自下而上合成是通过锂化二溴吡咯衍生物的一锅卤素舞蹈/Negishi 偶联实现的。易于获得的带有酯部分的二溴吡咯在-78°C 下10 分钟内顺利进行了卤素舞蹈。得到的 α-吡咯锂被金属转移到相应的有机锌物质上,然后在催化钯的存在下与芳基碘化物偶联以提供完全取代的吡咯。随后进行卤素 - 锂交换以仅在靠近酯部分的 β 位置掺入硼酸酯基团。这种合成中间体允许逐步二芳基化,用于层状蛋白 G、J、L 和 Z 的全合成。

  • Synthesis of Pulvinic Acid and Norbadione A Analogues by Suzuki–Miyaura Cross-Coupling of Benzylated Intermediates
    作者:Marine Desage-El Murr、Stéphanie Nowaczyk、Thierry Le Gall、Charles Mioskowski
    DOI:10.1002/ejoc.200500837
    日期:2006.3
    Pulvinic acid and norbadione A analogues can be prepared by Suzuki–Miyaura cross-coupling of functionalized arylboronic esters with appropriate vinyl triflates, in which the hydroxy functions are protected either with methyl or benzyl groups, the latter being cleaved in a more reliable fashion at the end of the synthetic sequence.
