Abstract: The 1,4-diazabicyclo[2.2.2]octane(DABCO) catalyzed reaction of cyclohexane-1,3-dione or dimedone with various aldehydes in acetonitrile resulted in the polysubstituted tetraketones, spiro dihydrofurans or 1,8-dioxo-xanthenes derivatives as main products respectively according to the structure of reactants and reaction conditions.

Key words: Tandem reaction, Dimedone, Spiro dihydrofuran, Tetraketone, 1,8-Dioxo-xanthene
