Dibenzofuran is an organic compound (C12H8O) consisting of two benzene rings fused to a central furan ring. Dibenzofuran can be synthesized by annealing and oxidative coupling methods of diphenyl ether, biphenyl derivatives, benzofuran, quinone. Most of the dibenzofuran-related natural products are metabolites of lichens or higher fungi. Lichen dibenzofurans appear to be formed by carbon-carbon oxidative coupling of orsellinic acid and its homologs.
