An ionic liquid-catalyzed synthesis of 2-amino-4,5-dihydro-4-arylpyrano[3,2-b]indole-3-carbonitrile derivatives through a novel three-component condensation of 3-hydroxyindole, aromatic aldehydes and malononitrile in the presence of silica supported ionic liquid of [pmim]HSO4SiO2 (silica supported 1-methyl-3-(triethoxysilylpropyl)imidazolium hydrogensulfate) as an efficient catalyst is described
