Copper-Catalysed Cascade Synthesis of Imidazolidine-Benzothiazole and Imidazolidine-Tetrazole Hybrid Heterocycles from Bis-thioureas by a Desulfurisation Strategy

Article abstract of DOI:10.1002/ejoc.201501096

The in situ generated bis-thioureas obtained by treating aryl/alkyl isothiocyanates with aliphatic 1,2-diamines, upon treatment with Cu^I or Cu^II salts, depending on their quantity and the reaction conditions, furnished either imidazo
