Chemo-Enzymatic Synthesis of Fmoc-Peptide Fragments
摘要:
Optically pure Fmoc-peptide fragments have been prepared via dicyclohexylcarbodiimide coupling of N-protected amino acids with amino acid esters, followed by enzyme-catalyzed ester hydrolysis by alcalase with a high concentration of organic solvent in a high yield.

AbstractCoupling of protected-amino acid halides (chloride, fluoride) mediated by commercial anion exchange resin for the solution phase synthesis of peptides is described. The reaction was carried out in an organic medium, circumventing the use of an organic base or an inorganic base. The coupling is fast, clean and racemization free. The anion exchange resin functions as a solid-phase basic scavenger
