Highly Enantioselective Three‐Component Povarov Reaction Catalyzed by SPINOL‐Phosphoric Acids.

Enantiopure SPINOL-phosphoric acids exhibit high activities and excellent diastereo- and enantioselectivities in the catalysis of the three-component Povarov reaction of N-vinylcarbamate (III), anilines (II) and aldehydes (I).
