products in satisfactory yields. The protocol is also applicable to amino acid derivatives, resulting in efficient and chemoselective N‐trifluoromethylation of di‐ and tri‐peptides with retention of configuration. A mechanism involving reductive elimination of Ag(III) intermediates to form N—CF3 bonds is proposed.
我们在此报告了N- H酰胺的直接N-三
氟甲基化。在AgOTf和2-
氟吡啶的促进下,各种酰胺与Selectfluor,
TMCSF 3和CsF的反应在室温下顺利进行,从而以令人满意的收率得到了相应的N-三
氟甲基化产物。该方案也适用于
