Magnetic graphene oxide functionalized with sulfonic acid (Fe 3O4-GO-SO3H) was used as a new recyclable nanocatalyst for one-pot synthesis of N-aryl-2-amino-1,6-naphthyridine derivatives under solvent free conditions. The catalyst could be easily recovered from the reaction mixture by an external magnet and reused without significant decrease in activity even after 4 runs. This nanocatalyst exhibited better activities to other commercially available sulfonic acid catalysts.

The new (α-Fe2O3)-MCM-41-SO3H catalyst was prepared directly through the reaction of chlorosulfonic acid with silica-coated nanoparticles (α-Fe2O3)-MCM-41 and used as a magnetically recyclable catalyst for an efficient one-pot synthesis of N-aryl-2-amino-1,6-naphthyridine derivatives. The catalyst with 10 wt% of loaded iron oxide nanoparticles could be recovered from the reaction mixture by an external magnet and reused without significant decrease in activity even after 5 runs. This new prepared catalyst exhibited better activities to other commercially available sulfonic acid catalysts.

A sequential three-component reaction of 3, 5-diarylidenepiperidm-4-one, malononitrile, and amine (such as aromatic amine, cyclopropanamine, and NH 4OAc) in acetic acid under microwave irradiation has been developed. In this one-pot reaction, a series of new N-substituted 2-amino-l, 6-naphthyridine derivatives were synthesized with excellent yields. This method has the advantages of operational simplicity and increased safety for small-scale fast synthesis of N-aryl 2-amino-l, 6-naphthyridines for biomedical screening.
