Abstract

A variety of 2‐arylnaphtho[1,2‐d]oxazole derivatives were efficiently synthesized in moderate to high yields by the reaction of aromatic aldehydes with 1‐amino‐2‐naphthol derivatives in the presence of triethylamine in refluxing ethanol in air. Seven new 2‐arylnaphtho[1,2‐d]oxazole derivatives were obtained and characterized by the spectral data and elemental analysis. In addition, the X‐ray crystal structures of 2‐[4‐(N,N‐dimethylamino)phenyl]naphtho[1,2‐d] oxzole (3d) and 1,1′‐bis(naphtho[1,2‐d]oxazol‐2‐yl)ferrocene (3n) have been determined.
