We report a new set of reactions based on the Pd-catalyzed alkylation of methylene C(sp(3))-H bonds of aliphatic quinolyl carboxamides with α-haloacetate and methyl iodide and applications in the stereoselective synthesis of various β-alkylated α-amino acids. These reactions represent the first generally applicable method for the catalytic alkylation of unconstrained and unactivated methylene C-H bonds
