A series of 14 imines containing furoxan and benzene rings has been prepared starting from isosafrole. The structure of reported compounds have been confirmed by elemental analysis, EI MS, UV, IR, and NMR spectroscopy. It is shown that, on treatment with Na2S2O4, the nitro group on the benzene ring was reduced to amino group, but the N→O group of the furoxan ring was not. The 1H- and 13C NMR signals
从异黄酮开始制备了一系列包含呋喃和苯环的14个亚胺。已通过元素分析,EI MS,UV,IR和NMR光谱确认了所报告化合物的结构。结果表明,在用Na 2 S 2 O 4处理时,苯环上的硝基被还原为氨基,而呋喃喃环上的N→O没有被还原。的1 H-和13个C NMR信号是基于它们的自旋-自旋分裂模式分配,在一些情况下,NOESY和HMBC谱使用。NOESY光谱表明,对于已报道的亚胺,苯和呋喃环不能共面;亚胺基具有E-构型。
