  摘要：

  The (3S,6S, 10S)-7/5 bicyclic lactam 8, designed as an external turn constraint, was synthesised by a new stereoselective route involving Eschenmoser condensation. The cyclic peptide 35 containing the integrin recognition motif GLDV added across the amino and carboxyl groups of the lactam external constraint 8 was prepared. (C) 2004 Elsevier Ltd.

  The (3S,6S,10S)-7/5 bicyclic lactam 4, designed as an external turn constraint, was synthesised by a new stereoselective route involving Eschenmoser condensation. Calculated preferred conformations compare well with the preferred solid state conformation. obtained by X-ray crystallography. The lactam 4 was not a turn mimic in its own right but Could be used as an external constraint to prepare the cyclic peptide 29 containing the integrin recognition motif GLDV. High-resolution NMR measurements were consistent with this compound having a single backbone conformation. (C) 2003 Elsevier Ltd. All rights reserved.
