gold to cyclize them! Gold‐catalyzed cycloisomerizativehydroalkylation of N‐allenyl amides affords regioselectively 4‐vinyl‐γ‐lactams. This transformation is stereospecific and takes place with a total axis‐to‐center chirality transfer. The required enantioenriched N‐allenyl amide is successfully obtained from an original Pd‐catalyzed dynamic kinetic asymmetric transformation (see scheme).
