Photoinduced electron transfer (PET) reactions of α-cyclopropyl-substituted ketones and triethylamine (TEA) were used to initiate the cyclopropylcarbinyl-homoallyl rearrangement. The intramolecular cyclization reaction onto triple bonds was performed yielding bicyclic and spirocyclic compounds. Furthermore, in some preliminary studies it was shown that even intramolecular aromatic substitutions are
α-环丙基取代的酮与三乙胺(TEA)的光诱导电子转移(PET)反应用于引发环丙基羰基-高烯丙基重排。进行到三键上的分子内环化反应,得到双环和螺环化合物。此外,在一些初步研究中表明,甚至分子内芳族取代也是可行的。
