Many reagents have been developed for cysteine-specific protein modification. However, few of them allow for multi-functionalization of a single Cys residue and disulfide bridging bioconjugation. Here the authors report 3-bromo-5-methylene pyrrolones as a simple, robust and versatile class of reagents for cysteine-specific protein modification.
