α,β-Unsaturated 1-acyl-1H-pyrroles are employed as enabling units for the construction of 1,4-dicarbonyl systems using the organocatalytic Stetter reaction. 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
α,β-不饱和 1-酰基-1H-吡咯用作使用有机催化 Stetter 反应构建 1,4-二羰基系统的使能单元。1-酰基-1H-吡咯单元增强的亲电性允许从脂肪醛催化构建稠合和非稠合吡喃酮,与芳香醛相容,并且还促进了涉及芳香醛和脂肪醛的反应的分子间变体.
