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.
Benzotriazole is a bicyclic nitrogen heterocycle formed by the fusion of the benzene ring with the 4,5-positions or the “d” site of 1H-1,2,3-triazole. The benzotriazoles are known as important intermediates in the preparation of organic products such as β-amido ketones, aldehydes, β-ketoesters, ionic liquid, and as reagents for acylation and thioacylation reactions. 1H-Benzotriazoles are also known to exhibit broad spectrum of pharmacological activities. There are numerous benzotriazole-based clinically used drugs in the market for the treatment of various diseases.
