transformation reaction using dimethylsulfoxonium methylide, a novel reaction was identified by which 5,6,7,8-tetrahydrocoumarin with the electron-withdrawing group at C3 was led to the spirobicyclo[3.1.0]hexane-cyclohexane derivative. Moreover, by establishing the scope of this reaction, it was confirmed that it is possible to apply this reaction to not only ring-fused α-pyrone derivatives but also a
通过应用使用二甲基亚砜基的亚甲基进行的骨架转化反应,鉴定出一种新的反应,该反应通过将在C3处具有吸电子基团的5,6,7,8-四氢香豆素生成螺双环[3.1.0]己烷-环己烷衍生物。此外,通过确定该反应的范围,已证实不仅可以以中等至良好的产率将该反应应用于环稠合的α-吡喃酮衍生物,而且还可以应用于烷基链取代的α-吡喃酮衍生物。
