Description

Application

Fmoc-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.
