  Synthesis ofN-chioroacetyl-?-glycopyranosylamines, derivatives of monosaccharides and lactose

  摘要：

  N-Chloroacetyl-beta-glycosylamines were synthesized from various monosaccharides (hexoses, pentoses, deoxysugars, uronic acids, and sugar phosphates) and a disaccharide (lactose) by N-acylation of the corresponding beta-glycosylamines with chloroacetic anhydride in DMF. In some cases, treatment of monosaccharides with NH3 in the presence of (NH4)CO3 in MeOH or aqueous MeOH was more efficient than the methods previously described, as it gave beta-glycosylamines in higher yields.

  The torsion angle around the N-glycoprotein linkage region (GlcNAc-Asn) is an important factor for presenting sugar on the cell surface which is crucial for many biological processes. Earlier studies using model and analogs showed that this important torsion angle is greatly influenced by substitutions in the sugar part. In the present work, uronic acid alkanamides and triazole derivatives have been designed and synthesized as newer analogs of N-glycoprotein linkage region to understand the influence of the carboxylic group on linkage region torsion as well as on molecular packing. Crystal structure of N-(beta-D-galacturonopyranosyl)acetamide is solved with the space group of P22(1)2(1). Comparison of the torsion angle and molecular packing of this compound with N-(beta-D-galactopyranosyl)acetamide showed that changing the C6-hydoxymethyl group to the carboxylic acid group has minimum influence on the N-glycosidic torsion angle, Phi(N) and significant influence on the molecular packing.
