A practical protocol for hydrotrifluoromethylthiolation of diazo compounds has been developed. A range of diazo compounds in combination with a nucleophilic SCF3 source provided access to valuable trifluoromethylthiolated compounds. Furthermore, a methodology for the first double trifluoromethylthiolation was developed.
A highly enantioselective one-potsynthesis of functionalized triflones, bearing a quaternary stereocenter, has been developed, exploiting the Michael reaction of α-(trifluoromethylsulfonyl) aryl acetic acidesters with N-acryloyl-1H-pyrazole catalyzed by commercially available Takemoto’s catalyst, followed by nucleophilic acyl substitution with alcohols. Preliminary investigations highlighted the
