CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe reactivity of the β-lactam ring towards nucleophiles has been investigated. Ring-opening reactions were performed on 3-allyl-β-lactams with CH3O–/CH3OH at room temperature and/or reflux. Lactam nucleus isomerization followed by N1–C2 bond cleavage and methanol Michael addition afforded substituted amino esters. The reactivity of the four-membered ring towards nucleophiles was found to depend on the substituents at the lactamic nitrogen and the C3 and C4 atoms. The ring-opening path is highlighted in this report.

| Abstract: | The reactivity of the β-lactam ring towards nucleophiles has been investigated. Ring-opening reactions were performed on 3-allyl-β-lactams with CH3O–/CH3OH at room temperature and/or reflux. Lactam nucleus isomerization followed by N1–C2 bond cleavage and methanol Michael addition afforded substituted amino esters. The reactivity of the four-membered ring towards nucleophiles was found to depend on the substituents at the lactamic nitrogen and the C3 and C4 atoms.
