  Preparation of glycosyl amino acids as building blocks for the combinatorial synthesis of neoglycoconjugates

  摘要：

  Several neoglycosyl amino acids possessing a sugar residue, a spacer and trifunctional amino acid moiety were synthesized both in solution and solid phase by activating the carboxylic group as its pentafluorophenyl ester for condensation. The methodology is useful for application in combinatorial syntheses of neoglycoconjugates as potential mimics for oligosaccharides. (C) 2002 Elsevier Science Ltd. All rights reserved.
