Some Tetrahydropyranyl Derivatives of Glycine, Serine and Urea

Naturevolume 192pages10691070 (1961) | Download Citation



THE provision of model compounds containing amino-acids or their analogues attached to sugars is of importance in evaluating the stability of the numerous types of carbohydrate-peptide linkages theoretically possible in mucoproteins. The ability of 2,3-dihydropyran to condense with —OH, —SH, and —NH2 groupings suggested a route to the glycosidically linked model compounds. The tetrahydropyran-2-yl derivatives so formed had the added advantage that the lability of the glycosidic linkage could be investigated without attendant complications such as acyl migration under alkaline conditions or Amadori re-arrangement catalysed by acid which might ensue in the presence of a hydroxyl substituent at C–2 of the pyran ring.
