A cerium(IV) sulfate tetrahydrate promoted oxidativecyclization of quinones with olefins is developed. It proceeds through a tandem [3+2]-cyclization–oxidative coupling–[3+2]-cyclization process, in which tetrahydrobenzodifurans were conveniently constructed in high yields. Moreover, this method exhibits a good functional-group tolerance and scalability.
