Furo[3,2-g]quinoline-4,9-diones were prepared through the reaction of active methylene compounds with 6,7-dichloroquinoline-5,8-dione, either by one step or two step method. Benzo[b]- and naphtol[1,2-b or 2,1-b]furo[3,2-g]quinolinediones were also prepared through the reaction of 6,7-dichloroquinoline-5,8-dione with phenols and naphtols in presence of pyridine. The structure of the synthesized compounds was determined by elemental and spectral analysis.
