phenoxyacetylhydrazine, was prepared from isoeugenoxyacetic acid. The hydrazide was condensed with aromatic aldehydes to give a series of 20 hydrazide‐hydrazones incorporating the furoxan ring. The structure of obtained compounds was determined by analytical and spectral data. It was demonstrated that the two sets of resonance signals in the 1H‐NMR and 13C‐NMR spectra of the examined hydrazide‐hydrazones
用异丁香氧基乙酸制备了一种新型的酰肼2-甲氧基-4-(3-甲基呋喃喃-4-基)-5-硝基苯氧基乙酰肼。将酰肼与芳族醛缩合,得到一系列20个带有呋喃环的酰肼-。通过分析和光谱数据确定获得的化合物的结构。结果表明,所检验的酰肼-azo酮在1 H-NMR和13 C-NMR光谱中的两组共振信号是由E N–C(O)和Z N–C(O)构象异构体引起的。构象交换的能垒由1确定在不同温度下的1 H NMR测量。在七个测试过的酰肼azo中,四种化合物在体外对人表皮癌(KB细胞)表现出抑制活性,IC 50 = 47、68、79和103μg/ mL。
