late-stage functionalization (LSF) of peptides represents a valuable strategy for the design of potent peptide pharmaceuticals by enabling rapid exploration of chemical diversity and offering novel opportunities for peptide conjugation. While the C(sp2 )-H activation of tryptophan (Trp) is well documented, the resurgence of radical chemistry is opening new avenues for the C-H functionalization of other

used as therapeutics or as tools in biomedical research. We have developed chemical modification methods that use spirooxindole oxiranederivatives for the synthesis of protein- and peptide-conjugates. In most cases, the epoxide group of the spirooxindole oxiranederivatives reacted to form a covalent bond with certain histidine residues and/or the N-terminal amino group of peptides and proteins. The
