Facile Synthesis of Fused Heterocycles through 2‐Bromobenzofurylglyoxal‐2‐arylhydrazones

Several new imidazo[1,2‐a]pyridine, pyrazolo[5,1‐a]imidazole, quinazolinone, 1,4‐benzothiazine, and pyrazole derivatives were synthesized by the reaction of 2‐bromobenz‐2‐furylglyoxal‐2‐arylhydrazones with different reagents. The structures of the new heterocycles were based on elemental analysis and spectral data.
