Rearrangement of Pyran Derivatives Obtained from Vinyl Malononitriles and Aldehydes via Vinylogous Aldol Reaction: A Novel Facile Method for the Synthesis of Dienamides
A novel one-pot approach to a variety dienamides from vinyl malononitriles and aldehydes via vinylogous aldol reaction was achieved by the electrolytic ring opening of the initially formed pyran derivatives under mild basic catalysis with good diastereoselectivity.
