Introducing a meta-Br in pyridine greatly enhances the reactivity of the phenylsulfonyl pyridinemoiety towards the free thiol group in a protein, which makes the protein ligation reaction completed within a couple of hours under physiological conditions. The high performance of these phenylsulfonyl pyridine tags in site-specific labeling of proteins have been demonstrated in a number of proteins.Rigid
