A domino reaction based on arylaldehydes and 1-acetylcyclopropanecarboxamides has been developed, which allows one-pot and efficient synthesis of structurally complex piperidine-2,4-diones with multiple functionalities under mild conditions. The overall transformation involves tandem aldol/intramolecular aza-Michael/(aldol)/Michael sequences. (C) 2010 Elsevier Ltd. All rights reserved.
