چكيده لاتين :
The one-pot domino Knoevenagel-type condensation/Michael reaction of aromatic, heteroaromatic and aliphatic aldehydes with 4-hydroxycoumarin in the presence of cellulose-supported butane sulfonic acid (Cell-BuSO3H) as a heterogeneous catalyst was investigated. Biscoumarins were obtained in good to excellent yields at short reaction times. The catalyst is reusable
