The synthesis of several substituted 2-amino-4 H-benzo[ h]chromene and 3-amino-1 H-benzo[ f]chromene derivatives was carried out using a one-pot three-component reaction of an arylaldehyde, malononitrile and a naphthol in H2O and in the presence of recyclable base supported ionic liquid like-phase as an efficient green catalyst.
