Aminocarboxylic acids (hydrazinocarboxylic acids) and estersP 0270 Amidocarbonylation of Aldehydes Utilizing Cobalt Oxide-Supported Gold Nano-

particles as a Heterogeneous Catalyst. — The transformation of aldehydes (I) and their equivalents (V) and (VII) affords N-acyl-α-amino acid derivatives (IV), (VI) and (VIII). The desired products are obtained in moderate to high yields under milder reac-tion conditions with respect to pressure and temperature compared to previous reports employing octacarbonyldicobalt as a catalyst. — (HAMASAKI, A.; LIU, X.; TOKUNAGA*, M.; Chem.
