Synthesis of macrocyclic thiolactone peptides via photochemical intramolecular radical acyl thiol–ene ligation†
Abstract
A photochemical acyl thiol–ene reaction can be used to rapidly cyclise fully unprotected peptides bearing both a thioacid and alkene to form peptide thiolactones. This strategy represents the first reported synthesis of peptide thiolactones under radical-mediated conditions.
