    DDQ-mediated oxidation of sp3 C–H bond for the direct synthesis of vicinal tricarbonyl compounds
    摘要:
    A facile and direct synthetic method was developed for the construction of vicinal tricarbonyl compounds (VTCs) in moderate to excellent yields (46-92%), by treating the readily available 1,3-dicarbonyl compounds with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) in the presence of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). The reaction pathway involves the DDQ-mediated oxidative activation of sp(3) C-H bond and subsequent coupling to TEMPO to form the key intermediate TEMPO-substrate adduct, which can be further converted to VTC products promoted by DDQ (C) 2014 Elsevier Ltd.

  • Allenamides Playing Domino: A Redox‐Neutral Photocatalytic Synthesis of Functionalized 2‐Aminofurans
    作者:Arianna Quintavalla、Ruben Veronesi、Laura Speziali、Ada Martinelli、Nelsi Zaccheroni、Liviana Mummolo、Marco Lombardo
    DOI:10.1002/adsc.202101015
    日期:2022.1.18
    designed synthetic approach also lies in the use of N-allenamides as substrates, which, after the addition of the first electrophilic radical, preserve a further reactive π-system, making possible the addition of a second α-keto radical and enabling the installation of a keto functionality at a remote position. The good yields, the broad scope, and the possibility to further synthetically elaborate
    提出了从 α-卤代羰基底物和N-丙二酰胺开始的功能化 2-氨基呋喃的光氧化还原催化合成。由于以下原因,该协议被证明是有效和可持续的:i ) 使用可见光作为绿色能源,ii ) 转化的氧化还原中性性质,允许避免添加剂和强氧化剂,iii ) 温和的反应条件和官能团耐受性,iv)低光催化剂负载和不存在过量试剂,v)在多米诺骨牌序列中一锅形成三个新键。根据我们的机械假设,转换被配置为双自由基-极性交叉反应,其中每产生一个 2-氨基呋喃分子,光催化剂被激发、氧化和还原两次。所设计的合成方法的新颖之处还在于使用N-丙二酰胺作为底物,在添加第一个亲电自由基后,它保留了进一步的反应性 π-系统,从而可以添加第二个 α-酮基自由基和能够在远程位置安装 keto 功能。良好的产量、​​广泛的范围以及进一步合成所获得的呋喃的可能性使该协议特别有希望用于构建有用的产品。

    A three-component Minisci reaction coupling of 1,3-dicarbonyl compounds with vinyl ethers and quinolines or isoquinolines under visible light is developed. The 1,3-dicarbonyl compound undergoes single-electron oxidation to afford an electrophilic 1,3-dicarbonyl radical under visible light irradiation. Due to the polarity of the free radical, the electrophilic radical adds to the electron-rich olefin
