Rapid Electrophilic Cysteine Arylation with Pyridinium Salts. [PDF]
Bioconjug Chem, 2022 Here, we present a series of fluorinated cationic reagents that enable rapid arylation of cysteine under mild conditions compatible with proteins and peptides. The highly polarized C-F bond and attractive nucleophile-electrophile Coulombic interactions substantially accelerate cysteine arylation, leading to unusually high rate constants on the order of
