The present invention provides novel synthetic methods for making acyclic secondary amines by reacting an azide with a compound bearing one or more C-H groups, catalyzed by a FeII-dipyrromethene complex. The acyclic secondary amines are thought to be formed through an intermolecular nitrene transfer. Also provided herein are methods of synthesizing protected (e.g., Boc- or Fmoc-protected) cyclic secondary amines (e.g., 5-, 6-, and 7- membered cyclic secondary amines) by reacting an azide that bears one or more C-H groups, catalyzed by a FeII-dipyrromethene complex. The protected cyclic secondary amines are thought to be formed through an intramolecular nitrene transfer and may be subsequently deprotected to yield cyclic secondary amines.

Herein, we describe a soluble iron(II)-phthalocyanine, [FeII(tBu4Pc)(py)2] (Pc = phthalocyaninato(2–)), as an effective catalyst in intramolecularC(sp3)–H bond amination, with alkyl azides as the nitrogen source, to afford the amination products in moderate to excellent yields with a broad substrate scope.
在此,我们描述了一种可溶性铁 ( II )-酞菁 [Fe II ( t Bu 4 Pc)(py) 2 ] (Pc = phthalocyaninato(2-)),作为分子内 C(sp 3 )-H的有效催化剂键胺化,以烷基叠氮化物为氮源,以中等至优异的产率提供胺化产物,底物范围广泛。
