Poly(ethylene glycol) (PEG-400) has been used as sustainable, nonvolatile, and environmental friendly reaction solvent for the synthesis of title compounds. Various diaryl pyrido[3,2-c]coumarins have been synthesized in one step by reacting 4-hydroxy-7-methyl-coumarin with α,β-unsaturated ketones in the presence of ammonium acetate. Further, in vitro antimicrobial (antibacterial and antifungal) activities
