Abstract
Mixed ketene acetals of enones of type 2 undergo stereoselective cydizations on a short column of silica gel to yield bicyclo[2.22]octanones of type 3. Enolates of vinylogous amides of types 6 and 8 cyclize directly upon reaction with methyl acrylate at -78 °C to form bicyclic β-amino ketones of types 7 and 9.
