Abstract

A novel, efficient and eco-friendly procedure for the synthesis of 14-aryl-14-dibenzo[a,j]xanthenes and 1,8-dioxo-octahydro-xanthenes is described through one-pot condensation of 2-naphthol and dimedone with aryl aldehydes in the presence of nano silica-supported ferric chloride under solvent-free conditions. The present approach offers several advantages such as short reaction times, high yields, easy purification, recovery and reusability of the catalyst.
