Irradiation of the title compounds gave cyclobutanols as the initial type II cyclization products, which were further photochemically rearranged to tricyclic β, γ-unsaturated ketones presumably via homolytic fission of cyclopropane ring followed by 1,2-alkyl migration.
标题化合物的辐照得到作为初始 II 型环化产物的
环丁醇,其进一步光
化学重排为
三环 β, γ-不饱和酮,推测是通过
环丙烷环的均裂裂变,然后是 1,2-烷基迁移。
