Peptidomimetics with tunable tertiary amide bond containing substituted β-proline and β-homoproline

Tunable cis/trans prolyl amide bond configuration in substituted β-proline (β-Pro) and β-homoproline (β-Hpro) homodimers was explored, based on position and nature of the substituent. Tertiary amide bond in β-proline (β2,3-substituted) dimers show distinct trans configuration and β-homoproline (β3-substituted) dimers preferably exhibited cis configuration.
