6-naphthyridines and pyrano[3,2-c]pyridines were selectively synthesized via microwave-assisted reactions controlled by the nature of the solvent. This has resulted in an efficient and promising synthetic method for constructing the 1,6-naphthyridine and pyrano[3,2-c]pyridine skeletons. solvent-dependent chemoselectivity - 1,6-naphthyridines - pyrano[3,2-c]pyridines

A sequential three-component reaction of 3,5-diarylidenepiperidin-4-one, malononitrile, and amine (such as aromatic amine, cyclopropanamine, and NH4OAc) in acetic acid under microwave irradiation has been developed. In this one-pot reaction, a series of new N-substituted 2-amino-1,6-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-1,6-naphthyridines for biomedical screening.
