Add acetic acid: A highly stereoselective N‐heterocycliccarbene (NHC)‐catalyzed formal [4+2] annulation between α,β‐unsaturated aldehydes and imidazolidinones for the synthesis of imidazoles has been developed. Acetic acid serves as a key additive to achieve high chemoselectivity for the formal [4+2] annulation product.
