    名称:
    Carbon Dioxide-Catalyzed Stereoselective Cyanation Reaction
    摘要:
    We report a Michael-type cyanation reaction of coumarins by using CO2 as a catalyst. The delivery of the nucleophilic cyanide was realized by catalytic amounts of CO2, which forms cyanoformate and bicarbonate in the presence of water. Under ambient conditions, CO2-catalyzed reactions afforded high chemo- and diastereoselectivity of beta-nitrile carbonyls, whereas only low reactivities were observed under argon or N-2. Computational and experimental data suggest the catalytic role of CO2, which functions as a Lewis acid, and a protecting group to mask the reactivity of the product, suppressing byproducts and polymerization. The utility of this convenient method was demonstrated by preparing biologically relevant heterocyclic compounds with ease.

  • 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。

    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.

    reaction selectivity is an eternal pursuit for chemists working in chemical synthesis. As part of this endeavor, our group has been exploring the possibility of constructing different natural product skeletons from the same simple starting materials by using different catalytic systems. In our previous work, an isoflavanone skeleton was obtained from the annulation of a salicylaldehyde and an alkyne
    控制反应选择性是从事化学合成工作的化学家们永恒的追求。作为这项工作的一部分,我们的小组一直在探索通过使用不同的催化体系,从相同的简单起始原料构建不同的天然产物骨架的可能性。在我们以前的工作中,当使用催化剂时,通过水杨醛炔烃的环化获得了异黄烷酮骨架。在本文中,显示了通过与相同的起始原料即末端炔烃水杨醛进行环化反应,只需切换为催化剂,即可有效地获得香豆素骨架。基于同位素替代实验,提出了一种合理的反应机理,用于这种新的环空反应。

    Overproduction of uric acid in the body leads to hyperuricemia, which is also closely related to gout. Uric acid production can be lowered by xanthine oxidase (XO) inhibitors. Inhibition of XO has also been proposed as a mechanism for improving cardiovascular health. Therefore, the search for new efficient XO inhibitors is an interesting topic in drug discovery. 3-Phenylcoumarins and 2-phenylbenzofurans
