| 摘 要： | 环十二碳酮(1)与苯基乙二醇(2)在对甲苯磺酸催化下的反应粗产物具有浓郁的花香,最初我们以为这种香气来源于缩酮2-苯基-1,4-二氧杂螺[4,11]十六烷(3):但该反应粗产物经反复重结晶后得到的无色晶体却没有香气、经红外、~1H核磁等谱图及碳氢分析鉴定该无色晶体确是缩酮3.既然缩酮3没有气味,则反应粗产物的香气必然来自反应中的副产物。薄层色谱分析表明,该反应中副产物较多。我们猜测,副反应可能主要来自2。

| Abstract: | The odoriferous material formed in the reaction of cyclododecanone and phenylethylene glycol under acidic condition, was not the ketal of cyclododecanone, but the acetal of phenylacetaldehyde with phenylethylene glycol. The cis-trans isomers of the acetal, I and II, were separated by chromatog., and the configurations were established via the anal. of their 1H NMR spectra. |
