General description

Fmoc-Lys(Boc)-OH is an amino acid derivative used as a reagent in Fmoc solid-phase peptide synthesis.

Application

Fmoc-Lys(Boc)-OH can be used for:
  • The solid-phase synthesis of pentasubstituted dihydroimidazolylbutyl dihydroimidazol-3-ium salts by coupling with p-methylbenzhydrylamine (MBHA) resin.
  • Fmoc-based peptide synthesis of bis-naphthalene diimide, a threading intercalator.
  • Synthesis of ε-Boc-ε-(3,5-bis-trifluoromethyl-benzyl)-α-Fmoc-L-Lysine to be used as 19F NMR based screening tool.
