The first diastereo‐ and enantioselective inverse electron demand hetero‐Diels–Alder reaction of β,γ‐unsaturated α‐ketoesters with allylsilanes is described. Chiral copper(II) catalysts successfully activate the β,γ‐unsaturated α‐ketoesters and promote the reaction with allylsilanes with excellent enantioselectivities. This process represents a new entry to chiral oxanes.
