The first synthesis of Tic-D-Phe Psi[CH2-CH2] isostere is described, which features diastereoselective alkylation of the tricyclic lactam 14. The use of this novel dipeptide isostere in the development of melanocortin agonists has been demonstrated by the synthesis of peptidomimetic 7 and non-peptidic ligand 27. Both compounds displayed significant binding and agonist potency at the MC4R. (C) 2005 Elsevier Ltd. All rights reserved.
