Appending a spirocyclopropane linkage to bicyclo[3.2.0]hept-2-ene is achieved by selective kinetic cyclopropanation of 6-methylenebicyclo[3.2.0]hept-2-ene. The resultant vinylcyclobutane undergoes [1,3] migration as the dominant thermal process. A minor cyclopropylcarbinyl (CPC) rearrangement product clearly implicates a diradical transition structure. The presence and absence of other potential thermal
将螺环丙烷连接到 双环[3.2.0]庚-2-烯 通过选择性的动力学环丙烷化来实现 6-亚甲基双环[3.2.0]庚-2-烯。结果乙烯基环丁烷经历[1,3]迁移是主要的热过程。较小的环丙基羰基(CPC)重排产物显然涉及双自由基过渡结构。是否存在其他潜在的热量产品,使我们能够构建详细的机械方案,以解决所有可行的动态过程。
