α,β-Unsaturated 1-acyl-1H-pyrroles are employed as enabling units for the construction of 1,4-dicarbonyl systems using the organocatalytic Stetterreaction. The enhanced electrophilicity of the 1-acyl-1H-pyrrole unit allows for the catalytic construction of fused and non-fused pyranones from aliphatic aldehydes, is compatible with aromatic aldehydes, and also facilitates an intermolecular variant of
