Synthesis of α-Trifluoromethylated Nitrogen Heterocycles
摘要:
The syntheses of various alpha-trifluoromethylated nitrogen heterocycles have been achieved from readily available alpha-(trifluoromethyl)homoallylamine through a ring-closing metathesis.

The iron(III)-catalyzed efficient strategy for the synthesis of α-substituted homoallylamines was accomplished via a cationic 2-aza-Cope rearrangement of aldimines, generated in situ by condensation of commercially available aldehydes and easily synthesizable 1,1-diphenylhomoallylamines. This reaction features a broad substrate scope with high yields and is conducted in an eco-friendly solvent, i.e
铁 ( III ) 催化合成 α-取代的高烯丙胺的有效策略是通过醛亚胺的阳离子 2-aza-Cope 重排实现的,醛亚胺是由市售的醛和易于合成的 1,1-二苯基高烯丙胺缩合原位产生的。该反应具有广泛的底物范围和高收率,并且在环保溶剂即碳酸二甲酯中进行。
