Abstract

We report a novel prosthetic group based on a heterocyclic methylsulfone derivative for the rapid, stable, and chemoselective (18)F-labeling of thiol-containing (bio)molecules under mild aqueous reaction conditions. Compared to established maleimide approaches, the new methodology displays some clear advantages for imaging probe development.
