A new method for the synthesis of [1,2,4]triazolo[4,3-a]pyridinium-3-aminides (1a and b) and an analogous [1,2,4]triazolo[4,3-a]pyrimidinium-3-aminide (1c) is described; an attempt to extend the procedure to the synthesis of related compounds (1d–g) resulted in dimerisation and rearrangement to yield the enamines (5a–d).
合成[1,2,4]三唑[4,3 - a ]吡啶-3-氨基(1a和b)和类似物[1,2,4]三唑[4,3- a ]的新方法描述了嘧啶-3-氨化物(1c);尝试将程序扩展到相关化合物的合成(1d – g),导致二聚反应和重排,生成烯胺(5a – d)。
