title: Copper catalyzed oxidative coupling of amines with formamides: a new approach for the synthesis of unsymmetrical urea derivatives.
abstract: Direct access to unsymmetrical urea derivatives via copper catalysed C-H/N-H coupling of formamides with amines has been developed at room temperature. This protocol is also applied to the synthesis of chiral urea derivatives.
