of allyl alcohols of the pinane series and of their epoxides in the presence of montmorillonite clay in intra- and intermolecular reactions was studied. Mutual transformations of (+)-trans-pinocarveol ((+)-2) and (−)-myrtenol ((−)-3a) were major reactions of these compounds on askanite–bentonite clay (Schemes 1 and 2). However, the two reactions gave different isomerization products, indicating that
研究了the石系列烯丙醇及其环氧化物在蒙脱土存在下在分子内和分子间反应的反应性。(+)-反式-香薄荷醇((+)- 2)和(-)-桃金娘酚((-)- 3a)的相互转化是这些化合物在on石-膨润土上的主要反应(方案1和2)。但是,这两个反应给出了不同的异构化产物,表明起始醇(+)- 2或(-)- 3a的反应性与在化合物中形成的相同化合物(+)- 2或(-)- 3的反应性不同。反应过程。(-)-顺式-和(+)-反-羟基苯甲酸酯((-)- 16和(+)- 12,分别),以及(-)-顺式-邻苯二酚环氧化物((-)- 20)与脂族和芳族化合物反应在石棉石-膨润土上的醛产生各种杂环化合物(方案4、5和7);反应路径取决于萜烯和醛的结构。
