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 c

The [2+2] carbonylative cycloaddition of N-alfa-aza-heteroaryl substituted imines with allyl bromide led partially to beta-lactams, which underwent isomerization to the more stable alfa,beta-unsaturated carbonyl compound. Pyrimidinone derivatives tog

Palladium-catalyzed cyclocarbonylation of N-heteroaryl-N-homoallyl amines led to γ- and δlactams with good yields and in a stereo- and regioselective way. The regio- and stereoselectivity of the methodology was investigated by changing the heterocy
