Traditional peptide synthesis iteratively elongates the chain from the C-terminus to the N-terminus (C-to-N), however, this process requires excess N-carbamate-protected amino acids and condensation reagents to minimize epimerization. Here, the authors report an alternative N-to-C elongation strategy by catalytic peptide thioacid formation and oxidative peptide bond formation without requiring condensation reagents and excessive protecting group manipulations.
