The title compounds, dimethyl 2-methoxy-6-(2,3,4-tri-O-acetyl-β-D-xylopyranosyl)amino-3,4- pyridinedicarboxylate, C₂₁H₂₆N₂O₁₂, (III), and dimethyl 2-methylthio-6-(2,3,4-tri-O-acetyl-β-D-xylopyranosyl)amino-3,4-pyridinedicarboxylate, C₂₁H₂₆N₂O₁₁S, (IV), are isomorphous. Molecules are linked by N—H

O hydrogen bonds [N

O 2.891 (4) for (III) and 2.913 (5)Å for (IV)], which generate chains in the a direction.
