Résumé

We report a one-pot methodology for the synthesis of N-alkylated 2-substituted azetidin-3-ones based on a tandem nucleophilic substitution followed by intramolecular Michael reaction of primary amines with alkyl 5-bromo-4-oxopent-2enoates, obtained in turn in three steps from levulinic acid. A mechanistic interpretation of these reactions and an attempted enantioselective approach are also described. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
