  2. Proline Scaffold

    One role of proline in proteins is that a β-turn of a peptide chain is being induced at its position. Two major conformations, cis or trans, of the corresponding amid bond will induce that the protein folds in a specific way.

  4. Specific platforms

    Asymmetric Phase-Transfer Reaction Phase-transfer alkylations e.g. with the chiral Maruoka catalyst result in unique α-mono substituted and α,α-disubstituted unnatural amino acids.

  6. α-Methyl and β,β-dimethyl amino acids

    α-Methyl and alkyl-amino acids can be produced by a number of platforms, where the (2S,4S)-4-methyl-2-phenyloxazolidin-5-one scaffold is one of the most popular one.

  7. Trifluoromethylated and other Fluoro-amino acids

    The incorporation of trifluoromethyl group carrying building blocks into peptides results in increased chemical and thermal stability, increased resistance to degradation by proteases, and enhanced lipophilicity.

  8. Arginine Analogues

    Trypsin (EC, an endopeptidase and natural protease found in the digestive system, cleaves peptide chains and proteins predominantly at the carboxyl side of the amino acids Lys and Arg (except when followed by Pro).
