has been developed, providing straightforward and efficient access to various benzoazoles and benzoazines. The present transition-metal-free protocol enables the dehydro-aromatization of tetrahydrobenzazoles and tetrahydroquinolines with molecularoxygen as the green oxidant, along with some other N-heterocycles. Hence, a broad range of heteroaromatic compounds are generated in moderate to good yields

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.
A simple and efficient method for the preparation ofpyrido[1,2-a]benzimidazoles by a copper-catalyzed inter- and intramolecular C–Ncouplingcascadeprocess was designed and carried out, and the products were obtained in moderate to excellent yields (up to 93 %).
