Selective intramolecular C—H amination via metalloradical activation of azides: synthesis of 1,3-diamines under neutral and nonoxidative conditions. One aspect of the present invention is the synthesis of 1,3-diamines by intramolecular C—H amination of sulfamoyl azides. More specifically, sulfamoyl azides may be selectively aminated via metalloradical activation of azides, preferably with Co(II) porphyrins. In a particularly preferred embodiment, the Co(II) porphyrin is a D

1,3-Diamines are an important class of compounds that are broadly found in natural products and are also widely used as building blocks in organic synthesis. Although the intramolecular C−H amination of N-alkylsulfamide derivatives is a reliable method for the construction of 1,3-diamine structures, the majority of these methods involve the use of a transition-metal catalyst. We herein report on a
