摘要：

beta-Enaminones have been synthesized in very good yield under solvent-free conditions from differently substituted amines and beta-diketones in the presence of Yb(OTf)(3) as catalyst. The method is applicable to cyclic and acyclic ketones, aromatic and aliphatic amines without differences. (c) 2007 Elsevier Ltd. All rights reserved.
