Hydrolysis of the GlcNAc oxazoline: deamidation and acyl rearrangement
Jha, Rajesh,Davis, Jeffrey T.
, p. 125 - 134 (1995)
The specific deamidation of 2-acetamido-1,3,4,6-tetra-O-acetyl-α-D-glucopyranose is achieved by p-toluenesulfonic acid-promoted hydrolysis of 2-methyl-(3,4,6-tri-O-acetyl-1,2-dideoxy-α-D-glucopyrano)--2-oxazoline 2 to give quantitative formation of the 1,3,4,6-tetra-O-actyl-2-amino-2-deoxy-α-D-glucopyranose p-toluenosulfonate (5d).This two-step procedure provides an amino sugar which may be readily acylated to give novel glycoconjugates.Altermatively, base-catalyzed O-1 --> N-2 acyl rearrangemet of the amino tosylate 5d gives the 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-D-glucopyranose 4 as a 9:1 mixture of α and β anomers.Thus, hydrolysis of GlcNAc oxazoline 2 gives the amino-ester 5 as the kinetic product and the amido-alcohol 4 as the thermodynamic product.Keywords: GlcNAc oxazoline; Deamidation; Acyl rearrangement

Binders of langerin could target vaccines to Langerhans cells for improved therapeutic effect. Since langerin has low affinity for monovalent glycan ligands, highly multivalent presentation has previously been key for targeting. Aiming to reduce the amoun
