  A new spirocyclic proline-based lactam as efficient type II′ β-turn inducing peptidomimetic

  摘要：

  A new proline-based spirotricyclic lactam is reported as an efficient type II' beta-turn inducing peptidomimetic. After investigations of the reverse turn properties by Computational techniques, the scaffold has been synthesized by a straightforward sequence relying on a key RCM reaction for the construction Of the spirocyclic lactams ring. For its conformational properties, the scaffold can be considered a privileged Structure to be employed as a mimic of the beta-turn motif of the potent antibiotic Gramicidin S. (C) 2008 Elsevier Ltd.
