开发了一种以苯乙炔或苯乙醛, 氯化铵和N,N-二甲基乙醇胺为原料, 在140 ℃条件下经三氟甲磺酸铁催化发生[2+2+1+1]环化反应, 其中N,N-二甲基乙醇胺既作为溶剂又作为单碳合成子参与构建3,5二芳基吡啶类化合物.

关键词: 3,5-二芳基吡啶, N,N-二甲基乙醇胺, 单碳合成子, 铁催化, 环合反应

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
