anticipated product, highly functionalized cyclopropanes were obtained. These novel cyclopropane structures are the result of the concomitant 1,2-migration of a dithiane thioether moiety and the eventual displacement of the acetate group, followed by the cyclization of the silyl enol ether.Key words: tricycles, SN2' cyclization, inductive effect, cyclopropane.
进行模型研究以探索通过使用甲硅烷基烯醇醚的 SN2' 环化以取代烯丙乙酸酯作为关键步骤来合成包含 C7-6C8 双键接头(类固醇编号)的稠合三环结构的可行性。获得了高度官能化的环丙烷,而不是预期的产物。这些新型环丙烷结构是二噻烷硫醚部分伴随 1,2-迁移和乙酸酯基团最终置换的结果,随后是甲硅烷基烯醇醚的环化。 关键词:三环,SN2' 环化,诱导效应, 环丙烷。
