A new imidazole-2-thione fused furazan biheterocyclic group was synthesized and its biological activity investigated. Nitrogen rich heterocycles, 1,2,5-oxadiazole (furazan) have been conveni ently fused. To accomplish this, we improved a strategy that silica gel supported solvent free micro wave dehydration of vicinal dioximes. The target "N,N’-diphenyl-4H-imidazo[4,5-c]furazan-5(6H) –thio ne" ...
