## Abstract Highly enantioselective Diels–Alder (DA) and inverse‐electron‐demand hetero‐Diels–Alder (HDA) reactions of β,γ‐unsaturated α‐ketoesters with cyclopentadiene catalyzed by chiral __N__,__N′__‐dioxide–Cu(OTf)~2~ (Tf=triflate) complexes have been developed. Quantitative conversion of β,γ‐un
