A novel construction of dibenzofuran-1,4-diones by oxidative cyclization of quinone-arenols.
A novel oxidative cyclization of quinone-arenols 5 leading to products 6 with a dibenzofuran-1,4-dione structure, which forms the core of several natural products, has been developed and applied to the synthesis of violet-quinone (4).
