  A facile synthesis of N-Z/Boc-protected 1,3,4-oxadiazole-based peptidomimetics employing peptidyl thiosemicarbazides

  摘要：

  Synthesis of 1,3,4-oxadiazole containing peptidomimetics is described by a p-TsCl/pyridine-mediated cyclization of the corresponding dipeptidyl thiosemicarbazides, which are readily prepared by coupling N-protected amino acid hydrazides with amino acid-derived isothiocyanato esters. Further, the protocol has also been extended for the synthesis of orthogonally protected 1,3,4-oxadiazole tethered mimetics as well. The synthetic route is simple and mild conditions are used so that the chirality of the starting amino acids is retained. (C) 2010 Elsevier Ltd. All rights reserved.
