AgF-mediated fluorinative cross-coupling of two olefins: Facile access to α-CF3 alkenes and β-CF3 ketones

A AgF-mediated fluorination with a concomitant cross-coupling between a gem-difluoroolefin and a non-fluorinated olefin is reported. This highly efficient method provides facile access to both α-CF3 alkenes and β-CF3 ketones, which otherwise remain challenging to be directly prepared. The application of this method is further demonstrated by the synthesis of bioactive isoxazoline derivatives. This approach represents a conceptually novel route to trifluoromethylated compounds that combines the in situ generation of the CF3 moiety and a C-H functionalization in a single reaction system.

Enantioselective synthesis of trifluoromethyl-substituted 2-isoxazolines: Asymmetric hydroxylamine/enone cascade reaction

(Figure Presented) Cuts both ways: The title reaction consists of an addition/cyclization/dehydration sequence and affords the biologically important chiral 3,5-diaryl-5-(trifluoromethyl)-2-isoxazolines 1 in excellent yields with high ee values. The flexi
