71 / An Fmoc-protected L-tyrosine building block carrying a β-D-galactose residue on the phenolic oxygen
GA441000: Fmoc-Tyr(Gal(Ac)4-β-D)-OH Pack Size:250 mg / 4-Nitrophenyl α-Kojobioside / pNP-α-KojobiosideC38H39NO14 733. 71 An Fmoc protected L tyrosine building block carrying a D galactose residue on the phenolic oxygen, designed for solid phase peptide synthesis (SPPS) of glycopeptides. The N Fmoc group is removed under standard base conditions (piperidine) during chain elongation, while the free carboxylic acid is available for coupling to the growing resin bound peptide. The sugar hydroxyl groups are protected as four acetate esters (Ac4), which
