  Synthesis of 1,2,4-oxadiazole-linked orthogonally urethane-protected dipeptide mimetics

  摘要：

  The synthesis of a new class of 1,2,4-oxadiazole-linked orthogonally urethane-protected dipeptide mimetics is described. The protocol employs a reaction between an N-protected amino acyl fluoride and an amino acid-derived amidoxime. All the three commonly employed urethanes have been used in this protocol for N-protection. The course of the reaction was found to be high yielding and all new compounds were well characterized by NMR and mass spectroscopy. The C-acyl amidoxime intermediate has also been isolated as a stable solid. (C) 2008 Elsevier Ltd. All rights reserved.
