A series of ester formylhydrazones were synthesised by the reaction of alkyl imidate hydrochlorides with formyl-hydrazine. Treatment of the ester formylhydrazones with acetic acid hydrazide, isonicotinic acid hydrazide, nicotinic acid hydrazide, and 4-hydroxybenzhydrazide resulted in the formation of either 4-acylamino-4H-1,2,4-triazoles or 2,5-disubstituted 1,3,4-oxadiazoles. 3-Alkyl-4-amino-4,5-dihydro-1H-1
通过亚胺酸烷基酯盐酸盐与甲酰肼反应合成了一系列酯甲酰腙。用乙酸酰肼、异烟酸酰肼、烟酸酰肼和 4-羟基苯甲酰肼处理酯甲酰腙导致形成 4-酰氨基-4H-1,2,4-三唑或 2,5-二取代的 1,3 ,4-恶二唑。3-烷基-4-氨基-4,5-二氢-1H-1,2,4-三唑-5-酮是通过酯甲酰腙与碳酰肼反应合成的。一些芳基氨基化合物是通过 4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones 与几种醛反应合成的。这些化合物通过元素分析、IR、1H NMR 和 UV 光谱技术进行了表征。
