Cobalt-mediated Reduction of C=N Bond. Synthesis of Methyl N-p-Toluenesulfonyl-1-phenylglycinate Catalyzed by Bis(dioximato)cobalt-Quinine Complexes

Reduction of C=N bond mediated by cobalt complexes was facilitated by the electron withdrawing substituents on the substrate.Catalytic hydrogenation of methyl N-p-toluenesulfonyl-1-imino-1-phenylacetate in the presence of quininium salt afforded the corresponding N-tosyl amino-ester in good yields.
