Popis: | Stereocontrolled methods are described for the synthesis of hitherto unreported pseudodiproline dimers in which a cyclopentane carboxylic acid is linked to a pyrrolidine residue by a stereochemically defined hydroxymethylene tether. These proline-cyclopentane (Pro-Cyp) dimers have interesting structural characteristics as seen in their X-ray crystal structures as well as their nuclear magnetic resonance (NMR) spectra in CDCl3. They can be considered to be novel Pro-Pro mimetics, which can be used to replace natural diproline sequences with potential applications in medicinal chemistry. They also represent a new concept in the peptidomimetic design of chimeric proline-based amino acids as carbocyclic hydroxyethylene isosteres of inhibitor molecules, in which the stereodefined bridging hydroxyl group can simulate a tetrahedral intermediate in an enzyme complex. |
