An electrochemical decarboxylative aminomethylation reaction of imidazo[1,2-a]pyridines with various N-substituted glycines in acetonitrile at room temperature has been described. The reaction could be conducted under light-free, catalyst-free, oxidant-free, and air conditions, affording the C3-aminomethylated imidazo[1,2-a]pyridines in good to high yields. Remarkably, N-aryl, N,N-dialkyl, and N-alkyl-N-aryl
已经描述了咪唑并[1,2- a ]吡啶与各种N-取代的甘氨酸在室温下在乙腈中的电化学脱羧氨甲基化反应。该反应可在无光照、无催化剂、无氧化剂和空气条件下进行,以良好至高收率得到C3-氨基甲基化咪唑并[1,2- a ]吡啶。值得注意的是,N-芳基、N-、N-二烷基和N-烷基-N-芳基甘氨酸在这种易于处理的方案中都具有良好的耐受性,这进一步扩展了具有生物活性的咪唑并[1,2- a ] 吡啶衍生物的化学空间.
