Now accessible: Sterically hindered vicinal tetrasubstitutedcarbon stereocenters, which are not accessible by asymmetric hydrogenation, were constructed by a catalytic asymmetric CC bond formation (see scheme; Dpp=diphenylphosphinoyl). By changing the Group 2 metal center, stereodivergent access to α,β‐tetrasubstituted α,β‐diamino esters was realized.
