Copper-catalyzed aliphatic C-H amination with an amidine moiety

Chen, Hui,Sanjaya, Stephen,Wang, Yi-Feng,Chiba, Shunsuke

supporting information, p. 212 - 215 (2013/04/23)

A method for amination of aliphatic C-H bonds of N-alkylamidines is described that utilizes Cu(OAc)2 as the catalyst in the presence of PhI(OAc)2 and K3PO4. The resulting products, dihydroimidazoles and tetrahydropyrimidines, could be converted into the corresponding diamines by hydride reduction.
