3,5-Diarylpyridines were effectively synthesized via [2+2+1+1] cyclization reaction catalyzed by Fe(OTf)3 at 140 ℃, using phenylacetylenes or phenylacetaldehydes, ammonium chloride and N,N-dimethylethanolamine as starting materials. N,N-Dimethylethanolamine was employed as both solvent and a single carbon synthon.

Key words: 3,5-diarylpyridine, N,N-dimethylethanolamine, single carbon synthon, iron catalyzed, cyclization
