    γ-叠氮基丁腈的一锅合成及其分子内环加成
    摘要:
    摘要 从市场上可买到的醛和氰基乙酸酯开始,已经开发了有效的克级一锅法制备叠氮基氰基丁酸酯及其酰胺化或脱羧衍生物。这些技术将(1)Knoevenagel缩合,(2)Corey-Chaykovsky环丙烷化和(3)供体-受体环丙烷与叠氮化物离子的亲核开环,以及(4)Krapcho脱羧或(4')酰胺化。通过分子内(3 + 2)-环加成将它们转化为四唑,证明了所得γ-叠氮腈的合成效用。在这种情况下,揭示了α-取代基的条件依赖性激活作用。热活化的叠氮化物-腈相互作用无法区分γ-叠氮腈中存在α电子吸电子取代基,而路易斯酸介导的(SnCl对于叠氮基氰基丁酸酯,4或TiCl 4)反应更容易进行。这使我们能够开发一种将叠氮基氰基丁酸酯转化为相应的四唑的有效方法。

  • Chemoselective Synthesis of Polycyclic Spiroindolines and Polysubstituted Pyrroles via the Domino Reaction of 2-Isocyanoethylindoles
    作者:Xiang Wang、Shun-Yi Wang、Shun-Jun Ji
    DOI:10.1021/jo501143m
    日期:2014.9.19
    Chemoselective 2-isocyanoethylindole-based domino reactions for the construction of polycyclic spiroindoline derivatives and polysubstituted pyrroles have been developed. The reaction of 2-isocyanoethylindoles and gem-diactivated olefins lead to the polycyclic spiroindoline derivatives (up to 92% yields) in EtOH under reflux conditions. Furthermore, the three-component reaction of 2-isocyanoethylindoles with gem-diactivated olefins and secondary amines afford polysubstituted pyrroles (in moderate yields) in CH3CN under reflux conditions.
