A one-pot regioselective synthesis of benzo[d]imidazo[2,1-b]thiazoles.

Benzo[d]imidazo[2,1-b]thiazole analogues were synthesized via a one-pot metal-free procedure. A series of benzene and pyridine substrates were employed to the methodology. The desired products were generated in moderate to good yields. The effect of substituent group had also been studied.
