The present application describes a novel type of picolinamide-cinchona organocatalyst that allows for the successful transformation of ketimines to chiral amines with very high enantioselectivities and with the highest TOFs reported for any particular organocatalyst to date. These organocatalysts have also been immobilized to a variety of solid supports, including magneto-nanoparticles.
