A convenient, efficient and green synthesis of N‐heteroaryl aminonaphthols has been developed by one‐pot, three‐component condensation of β‐naphthol, heteroaryl amines and substituted benzaldehydes under solvent‐free conditions at elevated temperature. The advantages of these reactions are simplicity of the reaction procedure, short reaction times, simple work‐up, catalyst‐free conditions and pure
A number of N-heteroaryl aminonaphthols (Betti bases) were prepared from the reaction of 2-naphthol, 3-aminopyridine, and aromatic aldehydes. Subsequent condensation of the prepared Betti bases with oxalyl chloride afforded the novel naphth[1,2-f][1,4]oxazepine-3,4-dione heterocycles in moderate to high yields. J.
