Benzofuran Dioxetanes, a New Class of Mutagenic Agents: Synthesis by Photooxygenation of Benzofuran Derivatives
Tetraphenylporphine-sensitized photooxygenation of benzofuran derivatives 1 afforded the corresponding benzofuran dioxetanes 2 in good yields.Allylic hydroperoxides 3 were formed regioselectively from 2,3-dimethyl-substituted benzofurans as minor products
