Hydrogenation of β-N-substituted enaminoesters in the presence of ruthenium catalysts
摘要:
beta-Aminoesters were prepared in two simple steps from beta-ketoesters derivatives and primary amines under mild conditions. Their hydrogenation was performed at 50 degrees C in the presence of several organometallic catalysts under acidic conditions. The new beta-N-substituted aminoesters were isolated in moderate to good yields. (C) 2010 Elsevier B.V. All rights reserved.
