异长叶稀Prins反应产物的结构表征

Two Products, Structure Characterization of the Prins Reactionof Isolongifolene

本文介绍了用分级洗脱柱色谱分离技术分离7-乙酰氧甲基异长叶环烯和7-乙酰氧甲基异长叶烯的方法,并用IR、'HNMR、MS等手段对两个化合物的结构进行了表征.

: 〈Ⅱ〉and 〈Ⅲ〉, two products of the Prins reaction of isolongifolene, are intermediates forpreparing a series of perfumery. This paper describes the method to separate 〈Ⅱ〉and〈Ⅲ〉 from product mix-ture(〈Ⅱ〉 +〈Ⅲ〉)through step elution column chromatography over silica gel (〈Ⅱ〉and 〈Ⅲ〉)have not beenseparated earlrier). In addition to,the structure of two product〈Ⅱ〉and 〈Ⅲ〉is characterized and confirmed.
