Preparation of pseudo glycoamino acid and its application to glycopeptide synthesis

2011

A pseudo glycoamino acid composed of a 1,3-diol structure and an amino acid was synthesized. This amino acid analog can act as an alternative acceptor to an amino acid containing GlcNAc for transglycosylation by Endo-M. A pseudo glycopeptide was synthesized using the pseudo glycoamino acid by a solid phase procedure. We attempted transglycosylation of N-glycan to the peptide using Endo-M.
