Synthesis of Substituted of Benzo[4,5]imidazo[1,2-a]pyrimidines through (3 + 2+1) Cyclization of 2-Aminobenzimidazole, Acetophenone, and N,N-Dimethylformamide as One-Carbon Synthon.

An efficient method for the construction of benzo[4,5]imidazo[1,2-a]pyrimidines using N,N-dimethylformamide as a one-carbon source and 2-aminobenzimidazoles and acetophenone as substrates through a one-pot, three-component cascade reaction is described. Spectra investigations indicated the fluorescent properties of selected products, exhibiting quantum yields 0.07-0.16 with maxima absorption at 266-294 nm and emission at 472-546 nm.
