Diels–Alder reaction of β-fluoro-β-nitrostyrenes with cyclic dienes (Beilstein Journal of Organic Chemistry)

Abstract The Diels–Alder reaction of β-fluoro-β-nitrostyrenes with cyclic 1,3-dienes was investigated. A series of novel monofluorinated norbornenes was prepared in up to 97% yield. The reaction with 1,3-cyclohexadiene permits the preparation of monofluorinated bicyclo[2.2.2]oct-2-enes. The kinetic data of the reactions with 1,3-cyclopentadiene and 1,3-cyclohexadiene were used to calculate activation parameters. Furthermore, the synthetic utility of the cycloadducts obtained was demonstrated. Beilstein J. Org. Chem. 2021, 17, 283–292. doi:10.3762/bjoc.17.27
