Iminoester hydrochlorides 1 have been synthesized. These compounds werethen converted into ester ethoxycarbonyl hydrazones 2, from which in turn a new seriesof substituted 4-amino-4,5-dihydro-1H-1,2,4-triazole-5-ones, 3, was then prepared.Finally a set of isatin imine derivatives 4 was obtained from the reaction of compounds 3with isatin. The structures of all the new synthesized compounds were confirmed byelemental analyses, IR, 1H-NMR and 13C-NMR spectra.
氨基酯盐酸盐 1 已被合成。这些化合物随后被转化为酯乙氧羰酰肼 2,并由此制备出一系列新的 4-氨基-4,5-二氢-1H-1,2,4-三唑-5-酮 3。所有新合成化合物的结构均通过元素分析、红外光谱、1H-NMR 和 13C-NMR 光谱得到证实。
