Beschreibung

Allgemeine Beschreibung

A building block for the introduction of thiaproline (Thz) during Fmoc SPPS. Thz has been employed as a masked cysteine residue to prevent self-ligation during native chemical ligation reactions (NCL) of peptide thioesters bearing an N-terminal Cys residue ^[6]. Once ligation is complete, the N-terminal Cys residue of the resultant peptide is unmasked by ring-opening the Thz residue by treatment with methoxyamine, thereby enabling its subsequent ligation to another peptide thioester fragment.
