چکیده
|
Dihydropyrano[3,2-b]chromenedione derivatives were synthesized in moderate-to-high yields in one-pot three-component reaction from the corresponding aromatic aldehydes,kojic acid,and dimedone,in the presence of catalytic amount of cecl 3·7h 2o/sio 2 as a nontoxic,reusable,inexpensive,and easily available reagent,under solvent-free conditions.
