No strain, no gain! The first transition metal‐catalyzed enantioselective α‐alkylation of cyclobutanones is reported. This method employs palladium catalysis and an electron‐deficient PHOX‐type ligand to afford all‐carbon α‐quaternary cyclobutanones in good to excellent yields and enantioselectivities (see scheme).
