The thesis contents methods for the selective activation and functionalization of C–H bonds of the C2 position of a tryptophan moiety incorporated into peptides. Palladium-catalyzed C-H arylation reactions applying diaryliodonium tosylates are shown, as well as ruthenium-catalyzed C-H arylation reactions applying aryl bromides and iodides, and ruthenium-catalyzed C-H alkylation reactions using vinyl ketones and acrylates. The developed procedures could be successfully applied to peptides for labeling with fluorophores, and ligation including twofold C-H activation.
