A versatile palladium-catalyzed carbonylative coupling protocol for the synthesis of carbamoyl phenylalanine derivatives has been described. Using a two-chamber COware system, this strategy also enables the efficient conversion of iodo-group-containing peptides into diverse carbamoyl motifs within a fully assembled peptide sequence, including bioactive scaffolds. This work provides a versatile tool for rapidly generating modified peptide libraries via targeted side chain tailoring of the phenylalanine residue.
Sharma et al. (2026) studied this question.
