Two new glycosyl amino acids N'~-Fmoc-Ser[Ac4-fl-D-Galp-(1 ~ 3)-Ac2-a-D-GalN3P]-OPf p and N'~-Fmoc-Thr[Ac4-/3-D-Galp-(1 ~ 3)-Ac2-a-D-GalN3p]-OPf p were synthesized. Glycosylation of N'~-Fmoc-Ser-OPf p or N ~-Fmoc-Thr-OPfp with protected/3-o-Gal-( 1 -~ 3)-D-GaIN 3 donors afforded the glycosyl amino a
