Substitution reactions of allylic alcohols 2 with various C-nucleophiles are described; in particular, 1,2-bis(trimethylsilyl)oxy)-cyclobutene in the presence of a Lewis acid leads to cyclobutanone derivatives which undergo an unusual acid-induced rearrangement affording spirocyclopropane structures.
描述了烯丙醇2与各种C-亲核试剂的取代反应;参见下文。特别是,在路易斯酸存在下的1,2-双(三甲基甲硅烷基)氧基)-环丁烯导致环丁酮衍生物,该衍生物经历了不寻常的酸诱导的重排,提供了螺环丙烷结构。
