all‐carbon quaternarystereocenters at the C3 position is important, but remains challenging. The present work demonstrates conjugate additions with catalysis by a chiral 1,10‐phenanthroline‐Pd complex (L1‐PdCl2) that exhibit complete regioselectivity with a high degree of enantioselectivity. These reactions afford chiral 3,3‐disubstituted succinimides having all‐carbon quaternarystereocenters with 40%−99%
