reactive α-bromocaranone from (+)-carene is reported. This intermediate was found to generate diverse chiral building blocks through radical or carbocation mediated cyclopropyl fragmentation reactions in moderate to excellent yields. Furthermore, the formation of an unexpected carvone derivative prompted several control studies that provided mechanistic insight into an unusual transformation. This study
报道了由 (+)- 芳烃轻松合成高反应性 α-溴卡拉酮。发现该中间体通过自由基或碳阳离子介导的环丙基裂解反应以中等至优异的产率产生多种手性结构单元。此外,意外的香芹酮衍生物的形成促使了几项对照研究,这些研究提供了对不寻常转变的机制洞察力。这项研究不仅展示了各种手性结构单元的合成,而且提供了对酮基卤代环丙烷反应性的深入了解。
