Tricyclic olefinic alcohols containing an unsymmetrically alkyl-substituted C, C-double bond were cyclized intramolecularly to their corresponding ethers under basic conditions: 9 12, 10 17 + 18, and 11 12(Scheme 3, Table 1). The reactivity is mainly due to relieve of ground state strain.
含有不对称烷基取代的C,C-双键三环烯属醇是在碱性条件下分子内环化到其相应的醚:9 12,10 17 + 18,和11 12 (方案3,表1) 。反应性主要归因于基态应变的减轻。
