FMOC-O-tert-Butyl-L-serine Usage And Synthesis
Chemical Propertieswhite to light yellow crystal powde
UsesFmoc-Ser(tBu)-OH is an N-terminal protected reagent used in the peptide synthesis. Some of the reported examples are:
  • Total synthesis of an antibiotic, daptomycin, by cyclization via a chemoselective serine ligation.
  • Preparation of MUC1, a T-cell helper peptide, using iterative pentafluorophenyl ester-mediated fragment condensations.
  • Linear solid-phase peptide synthesis of ubiquitin and diubiquitin.
