As simple as A, B, C : Non‐cysteine‐based reiterative fragment coupling of glycopeptides involves a metal‐free (TCEP) coupling of a peptidyl C‐terminal phenolic ester containing an ortho ‐disulfide moiety (A) with an N‐terminal glycopeptide whose C terminus is an alkyl thioester (B) to produce AB, whose N terminus contains an alkyl thioester. A AgCl‐mediated coupling of AB with peptide C then produces the tridomainal peptide ABC. TCEP=tris(2‐carboxyethyl)phosphine.
