Annulation of 2-nitrophenols and N,N-dialkyl-3-nitroanilines with styrenes in the presence of elemental sulfur and the base DABCO successfully yielded 2-benzyl benzoxazoles and 2-benzyl benzothiazoles, respectively.

2-aminobenzothiazoles often uses 2-aminothiophenol derivatives, which are not commercially abundant, as starting materials. Herein, we report a method for the annulation of C3-substituted nitroarenes and arylisothiocyanates towards the synthesis of 2-aminobenzothiazoles. Reactions proceeded in the presence of cobalt ferrite nanoparticles as a catalyst, DABCO as a base, and DMF as a promoter. The cobalt ferrite
