The direct regioselective allylation of in situgeneratedaldehydeacylanions has been achieved by synergisticNHC and Pd catalysis. It provides an efficient access to valuable β,γ‐unsaturated ketones under mild reaction conditions starting from easily accessible allylic carbonates and aldehydes without any preactivation. The synergisticcatalysis method demonstrated herein adds a new dimension to
