Synthesis of an external beta-turn based on the GLDV motif of cell adhesion proteins

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

Synthesis of an external β-turn based on the GLDV motif of cell adhesion proteins

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,
