  Synthesis of MEN11420, a glycosylated bicyclic peptide, by intramolecular double cyclization using a chloroimidazolinium coupling reagent

  摘要：

  The synthesis of MEN11420, a potent tachykinin receptor antagonist, has been achieved. The bicyclic glycosylated structure of MEN11420 was constructed via intramolecular double cyclization using CIP-mediated activation. The head to tail cyclization of the linear precursor, which contained an cy-amino acid at its C-terminus, proceeded so rapidly that no serious racemization was apparent at the activated carboxyl function. The desired product was obtained without the need for purification of the intermediates throughout the synthesis. (C) 2001 Elsevier Science Ltd. All rights reserved.
