Lighting up peptides: direct dehydroalanine formation from diselenides via Rose Bengal photocatalysis

Chem. Commun., 2025, Accepted Manuscript DOI: 10.1039/D5CC03361F, Communication Mateusz Waliczek, Martyna Strączek, Piotr Stefanowicz A visible-light-driven method for the site-selective conversion of diselenide-containing peptides to dehydroalanine (Dha) is presented. Using Rose Bengal as a photosensitizer in aqueous conditions, this photocatalytic process proceeds via oxidative...
