Synthesis of γ-Amino Esters by Copper-Catalyzed Intermolecular 1,2-Aminoalkylation of Alkenes with Amines and α-Bromoalkyl Esters

A new copper-catalyzed intermolecular 1,2-aminoalkylation of alkenes with α-bromoalkyl esters and amines for the synthesis of γ-amino esters is described. Employing the Cu(OTf) 2 and 2,2′-bipyridine catalytic system, the three-component reaction allows the formation of two new chemical bonds, including one C–C bond and one C–N bond, in a single reaction, and represents a new alkene difunctionalization using a radical strategy.
