摘要:

报道了由乙二醇有选择性的与氧化异佛尔酮4位或1位羰基形成缩酮化产物的NMR研究,介绍了通过与已知的缩酮化产物(2)的文献核磁图谱对照,以及与原料氧化异佛尔酮相应位置的NMR谱图对比来确定另一未见文献报道的缩酮化产物(3)的结构的方法,并对化合物(3)(3,5,5-三甲基-4,4-乙二氧基-2-环己烯酮)的氢谱和碳谱进行了归属.

Abstract:

In this paper,NMR characteristics of two keto-isophorone ketals were reported. By comparing with the NMR spectra of the compound (2)
reported in the references and with the NMR spectra of ketoisophorone itself, the 1H and 13C chemical shifts of keto-isophorone ketal (3) were assigned and analyzed and its structure was determined.

Key words: NMR, assignment, keto-isophorone, ketal, structure
