چکیده
|
3, 4- dihydropyrano [c] chromene derivatives were synthesized using sulfonic acid functionalized silica (sio2 -pr-so3 h) as a highly efficient heterogenous solid acid catalyst via one-pot three-component condensation of aromatic aldehydes with malononitrile and 4-hydroxycoumarin in excellent yields
