The first example of an α,β-unsaturated N-acylpyrrole undergoing a SmI2-mediated cyclization is reported. In contrast to other unsaturated units, the intermediate samarium enolate readily engages in aldol-type reactions, necessitating careful control of the reaction conditions.

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
