  • Zn(II)-Catalyzed One-Pot Synthesis of Coumarins from Ynamides and Salicylaldehydes
    作者:Huen Ji Yoo、So Won Youn
    DOI:10.1021/acs.orglett.9b01181
    日期:2019.5.3
    A highly efficient and straightforward synthesis of diversely substituted coumarins from ynamides and salicylaldehydes in the presence of Zn(II) catalyst has been developed. The sulfonamide moiety of ynamides was successfully recycled in this process, serving as an effective traceless directing group for high regioselectivity in the bond-forming event. The advantages of this protocol are good functional
    已经开发了在Zn(II)催化剂存在下由酰胺和水杨醛高效高效地直接合成各种取代的香豆素的方法。在此过程中,成功地将了酰胺的磺酰胺部分进行了再循环,在形成键的过程中,它是有效的无痕导向基团,具有很高的区域选择性。该方案的优点是良好的官能团耐受性,宽泛的底物范围,简单且高产率的反应,磺酰胺的回收/重复使用,廉价催化剂的低催化剂负载量以及这些优点,使该方法更具成本效益且更环保。
  • A transition-metal-free fast track to flavones and 3-arylcoumarins

    DOI:10.1039/c7cc02107k
    日期:——
    The procedure consists of a sequence of some reactions including an arylation/decarboxylation cascade and proceeds well in aqueous media to afford biologically interesting flavones and 3-arylcoumarins. This method exhibited excellent selectivity and functional group tolerance under mild conditions. The reaction also showed perfect efficacy for the preparation of styryl coumarins.

  • Rh(III)-Catalyzed C–H Activation/Cyclization of Benzamides and Diazonaphthalen-2(1<i>H</i>)-ones for Synthesis of Lactones
    作者:Renjie Chen、Sunliang Cui
    DOI:10.1021/acs.orglett.7b01728
    日期:2017.8.4
    A Rh(III)-catalyzed C–H activation/cyclization of benzamides and diazonaphthalen-2(1H)-ones for synthesis of lactones has been developed. In the presence of Rh(III) catalysis, the benzamides would form rhodacycle species and could be trapped by diazonaphthalen-2(1H)-ones for arylation, and the following intramolecular lactonization would rapidly furnish the products. Thus, the diazonaphthalen-2(1H)-ones
    已开发了Rh(III)催化苯甲酰胺和diazonaphthalen-2(1 H)-ones合成内酯的C–H活化/环化反应。在Rh(III)催化下,苯甲酰胺会形成rhodacycle物种,并可能被diazonaphthalen-2(1 H)-ones进行芳构化,并且随后的分子内内酯化作用将迅速提供该产物。因此,在Rh(III)催化中,首先发现重氮萘-2(1 H)-1是内酯化组分,同时进行了动力学同位素效应研究并提出了合理的反应机理。
