## Abstract The N‐heterocyclic carbene‐catalyzed conjugate umpolung of differently substituted α,β‐unsaturated aldehydes is described. Coupling of these compounds with a variety of trifluoromethylated ketones results in the selective formation of fluorinated γ‐butyrolactones. Using thiazolium‐deriv
