A fast photochemical C–C bond formation between cyclic ethers/acetals and olefins using di-tert-butyl peroxide (DTBP) was developed. This method provides easy access to 2-substituted cyclic ethers, and 2- or 4-substituted cyclic acetals. Acyl/formyl groups or diols can be obtained by the hydrolysis of the 2- or 4-substituted cyclic acetals, respectively. The reactions proceeded at room temperature
开发了使用二叔丁基过氧化物(DTBP)在环状醚/缩醛与烯烃之间快速形成光化学C-C键的方法。此方法可轻松获得2-取代的环醚和2-或4-取代的环缩醛。酰基/甲酰基或二醇可分别通过2-或4-取代的环状缩醛的水解获得。反应在室温下进行,得到预期的产物,收率良好至极好。在室温下0.5小时内完成高效反应,收率> 95%。
