Bachem also offers derivatives of phosphoserine and sulfoserine.
N-Terminal phosphoserine residues react with thioesters yielding highly reactive acylphosphates which spontaneously undergo an intramolecular O-N-shift allowing chemical ligation at such positions.


Building block for the synthesis of phosphoserine-containing peptides. Harris et al. observed a considerable extent of S-benzylation of adjacent Met residues during microwave-assisted TFA cleavage. Attard et al. recommend the use of cyclohexylamine/DCM (1:1) for Fmoc removal to minimize concomitant β-elimination.
