DOI: 10.1002/anie.202405344
Significance
Cyclic peptides have received increasing attention due to their improved stability and cell permeability, compared to linear peptides. The authors have established a cyclization at the side chain via carbonylation using in situ generated CO.
#
Comment
The cyclization proceeded at the side chain of Lys-Lys, Lys-Tyr, and Lys-Phe(4-NH2) regardless of the position of the complex peptide chain in good yields by the help of Cu catalysis.
