Abstract An umpolung process for the enantioselective functionalization of α-aminophosphonates with nucleophiles has been developed. This consists in a formal oxidation of tetrasubstituted α-aminophosphonates to α-iminophosphonates followed by an organocatalyzed nucleophilic addition reaction to the imine bond. The optimal enantioselectivity has been reached by studying the effect of the size of the
