role in medicinal and biological chemistry, synthetic methods to access non-natural methionine analogues remain underdeveloped. Using vitamin B2-photocatalysis, simple sulfides undergo radical α-C−H functionalization with unsaturated amino acid partners to deliver an array of new methionine derivatives. The approach also facilitates the chemoselective modification of peptide side-chains.
