A method for late-stage peptide ligation and macrocyclizationthrough rhodium-catalyzed C7-selective alkylation of tryptophan residues has been developed. This method is compatible with internal olefins and represents the first example of site-selective peptide C−H alkylation through deconjugative isomerization.
