  • One‐Step Synthesis of 3,4‐Disubstituted 2‐Oxazolidinones by Base‐Catalyzed CO <sub>2</sub> Fixation and Aza‐Michael Addition
    作者:Jere K. Mannisto、Aleksi Sahari、Kalle Lagerblom、Teemu Niemi、Martin Nieger、Gábor Sztanó、Timo Repo
    DOI:10.1002/chem.201902451
    日期:2019.8.6
    arylamine, aliphatic amine or phenylhydrazine, is performed under mild conditions. The regiospecific reaction displays good yields (av. 75 %) and excellent functional‐group compatibility. In addition, late‐stage functionalization of drug and drug‐like molecules is demonstrated. The experimental results suggest a mechanism consisting of several elementary steps: TMG‐assisted carboxylation of aniline; generation
    2-恶唑烷酮是饱和杂环化合物,在现代药物设计中是极具吸引力的目标。在这里,我们描述了一种新的,一步一步的方法,该方法使用CO 2作为羰基源和1,1,3,3-四甲基胍TMG)作为催化剂,通过aza-Michael加成反应来合成3,4-二取代的2-恶唑烷酮。模块化反应,发生在一个γ-化的迈克尔受体CO 2之间在温和条件下进行芳基胺,脂族胺或苯。区域特异性反应显示出良好的收率(平均75%)和出色的官能团相容性。此外,还展示了药物和类药物分子的后期功能化。实验结果表明该机理包括几个基本步骤:TMG辅助苯胺的羧化;氨基甲酸O烷基酯的生成; 以及通过分子内氮杂-迈克尔加成反应的最终成环步骤。
