  • Synergistic Indium and Silver Dual Catalysis: A Regioselective [2 + 2 + 1]-Oxidative <i>N</i>-Annulation Approach for the Diverse and Polyfunctionalized <i>N</i>-Arylpyrazoles
    作者:Raju S. Thombal、Yong Rok Lee
    DOI:10.1021/acs.orglett.8b02008
    日期:2018.8.3
    Indium(III)/silver(I)-catalyzed [2 + 2 + 1] annulation of arylhydrazine hydrochlorides with β-enamino esters via multicomponent reactions for the construction of diverse and multisubstituted N-arylpyrazoles has been demonstrated. The oxidative cycloaddition proceeds via a cascade triple Michael addition/elimination/air oxidation. This novel protocol provides a rapid and efficient synthetic route to
    已经证明了铟(III)/银(I)催化的芳基肼盐酸盐与β-烯胺酸酯通过多组分反应环化[2 + 2 +1],用于构建多种和多取代的N-芳基吡唑。氧化环加成通过级联三重迈克尔加成/消除/空气氧化进行。这一新颖的协议为各种3,4-二酯取代的N-芳基吡唑提供了一种快速有效的合成途径。合成的化合物进一步用于各种合成转化。
  • Palladium-Catalyzed C-S Bond Formation of Stable Enamines with Arene/Alkanethiols: Highly Regioselective Synthesis of β-Amino Sulfides
    作者:Yaojia Jiang、Gaohui Liang、Cong Zhang、Teck-Peng Loh
    DOI:10.1002/ejoc.201600588
    日期:2016.7
    A direct and regiocontrolled thiolation method to access β-amino sulfides through the palladium-catalyzed C(sp2)–H functionalization of stable enamines was described. The reaction was realized under mild conditions by adding an external phosphine ligand to prevent poisoning of the palladium catalyst by the sulfuric reagents. A possible mechanism was proposed according to the obtained results. The DFT
    描述了一种通过钯催化的稳定烯胺的 C(sp2)-H 官能化获得 β-氨基硫化物的直接和区域控制的硫醇化方法。该反应在温和条件下通过添加外部膦配体来实现,以防止钯催化剂被硫酸试剂中毒。根据所得结果提出了一种可能的机制。DFT 计算结果与实验数据一致,给出了 β-氨基硫化物的 E 异构体。该反应也以克规模进行,并显示出在有机合成中的潜在应用。
