摘　　要：N-酰腙类化合物在极性溶剂中存在着E/cis和E/trans两种异构体,本文利用元素分析、红外光谱、1D和2D核磁共振(NMR)波谱(包括1H NMR、13C NMR、1H-1H COSY、1H-13C HSQC、1H-13C HMBC和NOESY)等技术,对基于咔唑-三嗪并吲哚的新型N-酰腙衍生物3,即2-(5H-[1,2,4]三嗪[5,6-b]吲哚-3-硫基)-N'-(9-乙基咔唑-3-亚甲基)乙酰肼的两种异构体(E/cis和E/trans)的1H和13C NMR信号进行了全归属,测量了其偶合常数(J值)及两种异构体的含量,确定了其空间结构.N-acylhydrazone compounds have two isomers,E/cis and E/trans,in polar solvents.In this work,1H and 13C nuclear magnetic resonance(NMR)signals,coupling constants(J),and the spatial structures of the two isomers(E/cis and E/trans)of a novel carbazole-triazinoindole based N-acylhydrazone derivative 3,2-(5H-[1,2,4]triazine[5,6-b]indol-3-ylthio)-N'-(9-ethylcarbazol-3-ylmethylene)acetylhydrazine,were obtained by one-dimensional and two-dimensional NMR techniques,infrared spectroscopy(IR)and elemental analysis.The ratios of the two isomers were determined.
