摘要
The unprecedented formation of benzo[d]imidazo[2,1-b]thiazole during iron-catalyzed coupling of 2-aminobenzothiazole, aldehydes with nitroalkane in air has been observed. This unique transformation possibly occurs through a sequential aza-Henry reaction and subsequent intramolecular cyclization, followed by denitration. A variety of substituted benzo[d]imidazo[2,1-b]thiazole are obtained using this protocol.
