A cooperative catalyst consisting of a soft Lewis acid and a hard Brønsted base promoted the title reaction. The N‐thiophosphinoyl group on the ketimines was critical to surpass the high activation barrier through the soft–soft interaction of sulfur and copper. Mannich adducts with a tetrasubstituted stereogenic center were produced with excellent diastereo‐ and enantioselectivities. TANIAPHOS= ferrocenyl
