Abstract Attempted intramolecular allyl cation cycloaddition of trienol 2a, which contains a conjugated diene of Z-configuration, affords monocyclic trienes 3a,b, in contrast to related trienols known to produce [5,5]-bicyclic and/or [5,7]-bicyclic products. Cyclopentyl trienes 3a,b are isomeric with multifidene, an algal pheromone. Dimethyl trienol 6 fails to cyclize (under identical conditions),
摘要 与已知可产生 [5,5]-双环和/或 [5,7] 的相关三烯醇相比,尝试将含有 Z-构型共轭二烯的三烯醇 2a 进行分子内烯丙基阳离子环加成,得到单环三烯 3a,b -双环产品。环戊基三烯 3a、b 与 multifidene(一种藻类信息素)是同分异构体。二甲基三烯醇 6 无法环化(在相同条件下),但通过消除生成四烯 7。
