A one-pot multistep cyclization yielding thiadiazoloimidazole derivatives

A one-pot multistep cyclization yielding thiadiazoloimidazole derivatives

A versatile synthetic procedure is described to prepare the benzimidazole-fused 1,2,4-thiadiazoles 2a–c via a methanesulfonyl chloride initiated multistep cyclization involving the intramolecular reaction of an in-situ generated carbodiimide with a thiourea unit. The structure of the intricate heter...
