With ammonium acetate as catalyst, three-component 'one-pot' reaction of β-keto perfluoroalkanesulfones, aldehydes, and vinyl ethers proceeded smoothly and afforded tetrasubstituted 2,3-dihydropyrans in moderate to excellent yields. Both aromatic and alip

Catalyzed by piperidine, the reactions of β-keto polyfluoroalkanesulfones with aromatic aldehydes afforded the unexpected tetrasubstituted 2,3-dihydrofurans in good yields, probably proceeding through the normal Knoevenagel condensation products. This rea
