A straightforward method for loading a thiol cinchonine derivative onto the surface of gold nanoparticles is described. The material was found to be an effective heterogeneous catalyst in the asymmetric α-amination of β-ketoesters. A chiral thiol cinchonine derivative organocatalyst supported on the surface of gold nanoparticles has been used as an effective heterogeneous catalyst in the asymmetric α-amination of β-ketoesters.
