N-Protected amino acid allyl amides with an allylic leaving group can be used as substrates in palladium-catalyzed allylic alkylation. Whereas intermolecular allylations proceed with excellent yields under standard conditions for enolate reactions, the intramolecular version is not a trivial issue. N-Protected glycine amides preferentially form piperidinones through N-allylation, but the corresponding sarcosine derivatives provide γ-lactams in acceptable to good yields in dichloromethane, especially when the corresponding titanium enolates are formed.
