3-Acetylcoumarin was used as a precursor for the synthesis of novel fused heterocyclic compounds as chromeno[3,4-c]pyridine, chromeno[4,3-b]pyridine and pyrano[3,4-c]chromene derivatives in addition to the synthesis of 3-hetarylchromene derivatives. The chemical structures of newly synthesized compounds were avowed by means of spectral and analysis data. The novel synthesized compounds were estimated as antibacterial agents against Staphylococcus aureus and Escherichia coli bacteria.
