Enantiomerically pure N-Fmoc-S-Mob (S)-α-amino-ε-mercaptohexanoic acid (Amh) was synthesized in an efficient three step process from (L)-lysine via nucleophilic displacement of the pyridinium salt. An efficient method for Fmoc protection without any racemization is described. Incorporation of this unnatural amino acid into peptides and its complete deprotection was accomplished in high yield using
