The catalytic enantioselective Mannichreaction promoted by chiral bifunctional organocatalysts is described. The treatment of β-ketoesters with N-Boc-aldimines under mild reaction conditions afforded the corresponding β-amino β-ketoesters with excellent diastereoselectivities (up to 100:0 dr) and excellent enantioselectivities (up to 99% ee).
