Protocol for the Incorporation of γ‑Amino Acids into Peptides: Application to (−)-Shikimic Acid Based 2‑Amino-Methylcyclohexanecarboxylic Acids

The first example of a new protocol for the incorporation of γ-amino acids into peptides is reported. It involved a shikimic acid based stereoselective synthesis polyhydroxylated-2-nitromethylcyclohexanecarboxylic acids, which were directly incorporated into peptides.
