A will of iron: An iron‐catalyzedreductiveamination of aldehydes and ketones with anilines using molecular hydrogen is presented. Under mild conditions, high yields for a broad range of aryl, alkyl, and heterocyclic ketones as well as aldehydes are achieved.
Direct reductive amination of an aldehyde was carried out using a Hantzsch dihydropyridine as the reductant in the presence of a catalytic amount of scandium triflate. The reaction was highly selective towards aldehydes over ketones, and other reducible functional groups did not affect the reaction. (C) 2004 Elsevier Ltd. All rights reserved.
