Chiral oxazoline–pyridone ligands enable the enantioselective β,γ-dehydrogenation of cycloalkyl amides, with excellent enantio- and site-selectivity. The palladium-catalysed process provides access to chiral β,γ-unsaturated carbocycles and can also be combined with a C–H olefination step to form chiral γ-lactams.
