异长叶烯的Prins反应产物(Ⅰ)和(Ⅱ)是制备具有持久的柏木油和岩兰草油香气,并兼有龙涎香和鼠尾草油香气的香料(Ⅴ)和(Ⅵ)的中间体。本文报道了由长叶烯异构化不需将异长叶烯分离可直接在同一反应器和介质中进行Prins反应的工艺及结果。讨论了异长叶烯Prins反应的机理。
The prins reaction products (I) and (II) of isomerised spines are prepared from the flavors (V) and (VI) which have both the aroma of cedar oil and vetiver oil and the aroma of both ambergris and sage oil Intermediate. In this paper, we report the process and result of Prins reaction of longifolene isomerization without isolating longifolene directly in the same reactor and medium. The mechanism of Proline reaction of isoflurane was discussed.
