We report the high yield synthesis of novel 9-benzoyl-4-methylpyrano[2,3-f]chromene-2,8-dione derivatives obtained by the reaction of 8-formyl-7-hydroxy-4-methylcoumarin with various active methylene compounds. A mechanism of the tandem Knoevenagel condensation and cyclisation reaction is proposed. Structures of all compounds were elucidated on the basis of 1H and 13C NMR, and mass spectrometry, and elemental analysis.
