A simple palladium(II)-catalyzed intramolecular addition of vinylpalladium species to ketones initiated by the carbopalladation of alkynamides under mild conditions without a Pd(II)/Pd(0) redoxsystem was developed. This cascade reaction provides a new approach for the synthesis of highly substituted α-alkylidene-β-hydroxy-γ-lactams.
