The acid-catalyzed rearrangement of two enantiomerically pure epoxides derived from sesquiterpernic himachalenes, which are the main components of the essential oil of the Atlas cedar, has been studied using various Lewis and Bronsted acids. Several new polycyclic compounds have been obtained with different selectivities depending upon the catalysts used and the reaction conditions, and were fully
已经使用多种路易斯酸和布朗斯台德酸研究了倍半萜属喜马ale烯衍生的两种对映体纯的环氧化物的酸催化重排,这是阿特拉斯雪松精油的主要成分。根据所使用的催化剂和反应条件,已经获得了几种具有不同选择性的新型多环化合物,并通过光谱法对其进行了全面表征。还已经提出了解释反应混合物中观察到的不同化合物形成的机理。
