strategy for constructing maleimide-containing peptides and cyclicpeptides using Rh(III)-catalyzed tryptophan (Trp) (C7) alkenylation, which is challenging due to the inherent reactivity of the indole benzenoid ring. This method is scalable and exhibits broad substrate scope. The utility of this protocol could further be demonstrated by the synthesis of peptide conjugates with natural products and amino
