  • Copper‐Promoted O‐Arylation of the Phenol Side Chain of Tyrosine Using Triarylbismuthines
    作者:Adrien Le Roch、Martin Hébert、Alexandre Gagnon
    DOI:10.1002/ejoc.202000790
    日期:2020.9.7
    for the O‐arylation of the side chain of tyrosine using triarylbismuth reagents is reported. The reaction is performed in dichloromethane under oxygen at 50 °C in the presence of pyridine, is promoted by copper diacetate, shows excellent scope and functional group tolerance, and retains the integrity of the chiral center. The reactivity of other amino acids possessing a nucleophilic side chain under these

    of isoflavone via cross-coupling reaction of 3-trifloxychromone and triarylbismuth as a threefold arylating reagent. These isoflavones were further converted into 3,4-diarylpyrazole and 4,5-diarylpyrimidine using hydrazine hydrate and guanidinium chloride in the successive step in the same pot. Interestingly the formation of 3,4-diarylpyrazole was achieved in the shortest reaction time i.e., 30 min
    摘要本研究揭示了从3-trifloxychromone和triarylbismuth开始的一锅操作中3,4-二芳基吡唑和4,5-二芳基嘧啶的形成。一站式操作中,整个过程包括两个步骤。第一步通过作为三重芳基化试剂的3-三甲氧基色酮和三芳基的交叉偶联反应导致异黄酮的形成。在同一罐中的后续步骤中,使用将这些异黄酮进一步转化为3,4-二芳基吡唑和4,5-二芳基嘧啶。有趣的是,在最短的反应时间即在室温下也达到了30分钟,就形成了3,4-二芳基吡唑。 图形概要 提要此处介绍的工作描述了一种新的方法,该方法可通过一锅操作从3-三甲氧色酮和三芳基开始形成具有医学重要性的杂环3,4-二芳基吡唑和4,5-二芳基嘧啶
