    Highly Efficient Synthesis of Quinoxalinone-N-oxide via Tandem Nitrosation/Aerobic Oxidative C–N Bond Formation
    摘要:
    An efficient method for constructing quinoxalinone-N-oxides from cyanoacetanilides has been developed. This transformation can be achieved using inexpensive reagents and molecular oxygen under mild conditions, thus offering a practical pathway to quinoxalinone-containing pharmaceuticals such as ataquimast and opaviraline.

  • Acyl Radicals from α-Keto Acids: Metal-Free Visible-Light-Promoted Acylation of Heterocycles
    作者:Hu-Lin Zhu、Fan-Lin Zeng、Xiao-Lan Chen、Kai Sun、Hao-Cong Li、Xiao-Ya Yuan、Ling-Bo Qu、Bing Yu

    A general and metal-free visible-light-induced decarboxylative arylation procedure at room temperature was described for the construction of acylated heterocyclic derivatives, such as benzimidazo/indolo[2,1-a]isoquinolin-6(5H)-ones, aroylazaspiro[4.5]trienones, thioflavones, and so on. This practical arylation procedure was conducted by using 2,4,5,6-tetra(9H-carbazol-9-yl)isophthalonitrile (4CzIPN)

    日期:2021.2.19
    We report both an intermolecular C–H amination of arenes to access N-methylanilines and an intramolecular variant for the synthesis of tetrahydroquinolines. A newly developed, highly electrophilic aminating reagent was key for the direct synthesis of unprotected N-methylanilines from simple arenes. The reactions display a broad functional group tolerance and employ catalytic amounts of a benign iron

    In some aspects, the present disclosure provides methods of aminating an aromatic compound comprising reacting an aminating agent with an aromatic compound in the presence of a rhodium catalyst. In some embodiments, the methods may comprise aminating an aromatic compound which contains multiple different functional groups. The methods described herein may also be used to create bicyclic system comprising reacting an intramolecular aminating agent with an aromatic ring to obtain a second ring containing a nitrogen atom. In another aspect, the methods described herein may also be used to create a cyclic aliphatic cyclic/poly cyclic amine system comprising a reacting an intramolecular aminating agent by insertion into a C(sp3)-H bond.

    key functional groups in pharmaceuticals, agrochemicals, and functional materials, as well as in bioactive natural products. However, there is a dearth of generally applicable methods for the direct replacement of aryl hydrogens with NH2/NH(alkyl) moieties. Here, we present a mild dirhodium-catalyzed C-H amination for conversion of structurally diverse monocyclic and fused aromatics to the corresponding
    伯胺和 N-烷基芳胺基序是药物、农用化学品、功能材料以及生物活性天然产物中的关键官能团。然而,缺乏普遍适用的用NH2/NH(烷基)部分直接取代芳基氢的方法。在这里,我们提出了一种温和的二铑催化的 CH 胺化反应,使用 NH2/NH(烷基)-O-(磺酰基)羟胺作为胺化剂,将结构多样的单环和稠合芳族化合物转化为相应的伯胺和 N-烷基芳胺;相对较弱的RSO2O-N键起到内氧化剂的作用。该方法操作简单,可扩展,并且在环境温度或低于环境温度下快速,以中等至良好的产率提供芳胺,并具有良好的区域选择性。它可以很容易地扩展到稠合N-杂环的合成。
