Efficient methods for the synthesis of aminomethylated azaindole derivatives via domino copper-catalyzed multicomponent coupling and cyclization have been developed. Using various secondary amines and aldehydes, N-substituted 3-ethynyl-4-aminopyridine was converted to substituted azaindoles in moderate to excellent yields. By use of a 3,4-diaminopyridine derivative bearing two alkynyl groups, the corresponding
已经开发了通过多米诺铜催化的多组分偶联和环化合成氨基甲基化的氮杂吲哚衍生物的有效方法。使用各种仲胺和醛,将N-取代的3-乙炔基-4-氨基吡啶以中等至优异的产率转化为取代的氮杂吲哚。通过使用带有两个炔基的3,4-二氨基吡啶衍生物,通过可控的逐步环化合成相应的吡咯稠合的氮杂吲哚。
