## Abstract Cycloaddition of dichloroketene to 3‐, 7‐, and 17‐methylene steroids affords the corresponding spirodichlorocyclobutanones, which can be reduced to monochloro‐ and unsubstituted spirocyclobutanones. Selective cycloaddition to the exo‐double bond is observed in the reaction of 3β‐acetoxy
