The mild basicionicliquids, 1,8-diazabicyclo[5.4.0]-undec-7-en-8-ium acetate, pyrrolidinium acetate, pyrrolidinium formate, piperidinium acetate, piperidinium formate, N-methylimidazolium formate, and 3-hydroxypropanaminium acetate catalyzed three-componentsynthesis of 2-amino-3-cyano-4-aryl-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene and hydroxyl naphthalene-1,4-dione derivatives under ambient
A one-pot procedure for synthesis of hydroxyl naphthalene-1,4-dione derivatives via a three-component reaction of 2-hydroxynaphthalene-1,4-dione, aromatic aldehydes and heterocyclic or carbocyclic amines is developed. MCM-41 nanoporous catalyst is effective, easy recovery, reusable and makes work-up easy. This approach is clean and environmentally friendly. The structures of the new compounds were confirmed by FT-IR, H-1 NMR,C-13 NMR, and elemental analysis. (C) 2015 Elsevier Ltd. All rights reserved.
