The enantioselectiveN‐heterocycliccarbenecatalyzed [3+3] annulation of α‐bromoenals by dynamic kinetic resolution (DKR) of enamines and normal resolution of α,α‐disubstituted imines were developed. The corresponding substituted dihydropyridones were isolated in good yields with excellent diastereo‐ and enantioselectivities, and a high selective factor (up to 83) was realized for the resolution of
