A series of ester formylhydrazones 2 were synthesized from the reaction of alkyl imidate hydrochlorides 1 with formylhydrazine. Treatment of 2 with hydrazine hydrate, ethyl carbazate and tert-butyl carbazate led to the formation of 3-alkyl-4-amino-, 3-alkyl-4-ethoxycarbonylamino- and 3-alkyl-4-tert-butoxycar-bonylamino-4H-1,2,4-triazoles 3–5, respectively. Reaction of compounds 2 with formylhydrazine
一系列酯formylhydrazones的2从烷基酰亚胺盐酸盐的反应,合成1用甲酰肼。用水合肼,氨基甲酸乙酯和氨基甲酸叔丁酯处理2,导致形成3-烷基-4-氨基-,3-烷基-4-乙氧基羰基氨基-和3-烷基-4-叔丁氧基-羰基氨基-4。H -1,2,4-三唑3-5。化合物2与甲酰肼反应,得到N,N′-二甲酰肼6。化合物2与2,5-二甲氧基四氢呋喃反应,得到3-烷基-4-(1H-吡咯-1-基)-4H -1,2,4-三唑8。
