Copper-mediated intramolecular C(sp3)–H amination of alicyclic amines: regio- and site-selective access to imidazolidin-4-one

Herein, we describe a copper-mediated intramolecular C(sp 3 )–H amination of alicyclic amine, affording the valuable imidazolidin-4-one derivatives with excellent chemo- and regio-selectivity.
