Abstract

This research describes application of a mesoporous nanostructured material based on basic ionic liquid anchored to silica, i.e. nano-2-(dimethylamino)-N-(silica-n-propyl)-N,N-dimethylethanaminium chloride {nano-[DMSPDE][Cl]}, as a highly effective and heterogeneous nanocatalyst for the production of 2-amino-4H-chromenes. The one-pot multi-component reaction of aromatic aldehydes with malononitrile and 1-naphthol in the presence of nano-[DMSPDE][Cl] under solvent-free conditions affords the title compounds with high yields in short times.
