Methyl α-l-sorboside monohydrate

Methyl l-sorboside monohydrate, C₇H₁₄O₆·H₂O, was prepared from the rare sugar l-sorbose, C₆H₁₂O₆, and crystallized. It was confirmed that methyl l-sorboside formed α-pyran-ose with a ² C ₅ conformation and crystallized with one water molecule of crystallization. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming a three-dimensional network. The unit-cell volume of the title compound, methyl l-sorboside monohydrate, is 481.13 (2) ų (Z = 2), which is about 108.16 ų (29.0%) greater than that of half the amount of the chemical α-l-sorbose [745.94 (2) ų (Z = 4)].
