Résumé : A variety of propenamidines 3 have been reacted with enamines of cyclopentanone and cyclohexanone giving after hydrolysis of the Stork enamine 6 2-8-amidinoethylcyclopentanones 8 and -hexanones -. This reaction illustrates the electrophilic character of the C=C double bond due to the conjugated amidine function, thus providing with propenamidines 3 a new class of Michael acceptors for enamines. © 1989, Taylor & Francis Group, LLC.
