The development of new chiral ligand constitutes the cornerstone of asymmetric catalysis. An asymmetric synthesis of α,α-dialkylated pyrrolidinones enabled by Ni-catalyzed reductive carbamoyl-alkylation of 1,1-disubstituted alkene- tethered carbamoyl chlorides and primary alkyl iodides is presented. After extensive investigation of Quinim ligands, it is found that the evolution of chiral ligand p-tolQuinim to 1-NapQuinim is critical for formation of the all-carbon quaternary center in high yield and enantioselectivity and broad functional group tolerance. The newly developed catalytic system that combines nickel salts and the 1-NapQuinim ligand also improves both the yield and enantioselectivity in the synthesis of α-monoalkylated γ-lactams.

Key words: Quinim ligand, nickel catalysis, quaternary stereocenters, γ-lactam
