series of 1-oxojaeskeanadiol esters, whose structure was established by spectroscopic data and chemical reactions, including correlation with jaeskeanadiol. Treatment of these esters with potassiumhydroxide gave two polienonic products, resulting from the stepwise elimination of the ester group and one water molecule. Both compounds were unstable; the dienone underwent rapid deconjugation via a 1,5-sigmatropic
摘要 Ferula community 有毒品种的果实产生了一系列1-oxojaeskeanadiol 酯,其结构是通过光谱数据和化学反应确定的,包括与jaeskeanadiol 的相关性。用氢氧化钾处理这些酯得到两种多烯酮产物,这是由于酯基团和一个水分子的逐步消除而产生的。两种化合物都不稳定;二烯酮通过 1,5-sigmatropic 氢位移经历快速解偶联,而三烯酮在共轭体系的末端键在空气中被氧化。在水果中没有发现有毒的异戊二烯化香豆素。
