Chemical post-translational methods allow convergent side-chain editing of proteins without needing to resort to genetic intervention. Current approaches that allow the creation of constitutionally native side chains via C–C bond formation, using off-protein carbon-centered C· radicals added to unnatural amino acid radical acceptor (SOMOphile, singly occupied molecular orbital (SOMO)) “tags” such as dehydroalanine, are benign and wide-ranging. However, they also typically create epimeric mixtures of d/l-residues. Here, we describe a light-mediated desulfurative method that, through the creation and reaction of stereoretained on-proteinl-alanyl Cβ· radicals, allows Cβ–Hγ, Cβ–Oγ, Cβ–Seγ, Cβ–Bγ, and Cβ–Cγ bond formation to flexibly generate site-selectively edited proteins with full retention of native stereochemistry under mild conditions from a natural amino acid precursor. This methodology shows great potential to explore protein side-chain diversity and function and in the construction of useful bioconjugates. Cys-arylation and then C−S bond scission creates on-proteinl-alanyl Cβ· radicals that allow Cβ−Hγ, Cβ−Oγ, Cβ−Seγ, Cβ−Bγ, and Cβ−Cγ bond formation to edit proteins with full retention of native stereochemistry.
