Keeping in view the recent success of molecular hybridization technique in drug design, 2,4-diarylpyrano[3,2-c]chromen-5(4H)-ones as conjugates of coumarins and chalcones have been designed and synthesized in the present study. The catalytic efficiency of
Bi(OTf)3-catalyzed solvent-free synthesis of pyrano[3,2-c]coumarins through a tandem addition/annulation reaction between chalcones and 4-hydroxycoumarins
