Key words
rhodium catalysis - C–H functionalization - macrocyclic peptides - tryptophan-containing peptides
Significance
Late-stage functionalization plays an inherent role in the construction of peptides and macrocyclic peptides. In the present study, the authors developed a Rh(III)-catalyzed alkenylation of tryptophan-containing peptides for the synthesis of maleimide-decorated peptides and macrocyclic peptides.
#
Comment
Rh(III)-catalyzed alkenylation of tryptophan-containing peptides proceeded smoothly to deliver maleimide-decorated peptides in good yields with excellent selectivity. The intramolecular reaction of maleimide-decorated peptides produced macrocyclic peptides.
