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.

Standard approaches

Diethyl-acetamidomalonate Route: The probably most widely used first approach to unnatural amino acids goes via alkylation of diethyl acetamidomalonate.

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.

Homologization of natural amino acids

Several platforms are available to display the whole assortment of homo-amino acids, as well as the higher homologues β2-, β3-, their double substituted derivatives β2,2,2-, β3,3-, and corresponding γ-amino acids.
