[ 1 ] - β-Cyclodextrain sulfonic acid as a biodegradable solid catalyst in benzoxanthenes synthesis

A new and efficient synthesis of benzoxanthene drivatives from the three-component condensation reaction ofaryl aldehydes and β-naphthol under solvent-free conditions in the presence of β-cyclodextrin sulfonic acid, as an efficient heterogeneous solid acid catalyst with excellent yields and short reaction time is presented
