Zhang, Zhenzhen published the artcileSilver-Mediated N-Trifluoromethylation of Amides and Peptides, Recommanded Product: ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol, the publication is Chinese Journal of Chemistry (2020), 38(9), 924-928, database is CAplus.
The direct N-trifluoromethylation of N-H amides was reported. Promoted by AgOTf and 2-fluoropyridine, the reaction of a variety of amides with Selectfluor, TMSCF3 and CsF proceeded smoothly at room temperature leading to the corresponding N-trifluoromethylated products in satisfactory yields. The protocol was 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 was proposed.
