  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.

  A set of N-acyllactosylamine derivatives containing a terminal amino group in aglycons of various lengths (up to 16 atoms) and various hydrophilicities were synthesized. The aglycons were represented by di-, tri-, and pentapeptides containing glycine and serine residues and by aglycons containing fragments of tartaric acid or a tertiary amine.

  Efficient monoalkylation of a series of primary and secondary amines was demonstrated with the use ofN-chloroacetylglycosylamines derived fromd-glucose,d-galactose,d-mannose,N-acetyl-d-glucosamine, and lactose. The reaction was shown to be useful for incorporation of carbohydrate residues into physiologically active compounds.

  A method for the synthesis of glycoclusters by N-alkylation of N-glycyl-β-lactosylamine with N-chloroacetyl derivatives of β-lactosylamine and N,N’-iminodiacetyldilactosylamine has been developed. The glycoclusters obtained with two and three lactosylamine residues with the amino group in the spacer were found to be suitable for further conjugation with carboxy-containing physiologically active compounds.
