A cobalt-catalyzed regio- and enantioselective γ-amination of β,γ-unsaturated N-acylpyrazoles that delivers the corresponding γ-amination products in good regio- and enantioselectivity has been established. Moreover, the nitrogen-containing compounds could be easily synthesized. DFT calculations have been provided to explain regio- and enantioselectivity for this γ-amination. The chiral γ-amination products were readily converted into the chiral γ-amino acid derivatives.
