Article abstract of DOI:10.1039/c8nj00718g

Bis-coumarins and xanthenes are privileged compounds with diverse pharmaceutical activities. Hence, we introduce here an efficient synthesis of 3,3′-arylmethylene-bis-(4-hydroxycoumarin-3-yl) and 1,8-dioxooctahydroxanthenes under the soft catalytic activi
