An efficient metal-free desulfurization strategy promoted by Togni-II reagent

Abstract

Desulfurization is a versatile synthetic tool in organic synthesis, particularly in peptide chemistry, where it offers an effective conversion strategy for compounds that contain mercaptan groups. In this study, we present a metal-free desulfurization method for amino acids and peptides using a Togni-II reagent as a radical initiator. Our method showed excellent efficiency and extensive substrate tolerance, circumventing the formation of radical adducts caused by VA-044. The obtained results further expand the applicability of Togni-II reagent as a key promotor in radical-based reactions.
