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-pyranose with a 2
C
5 conformation and crystallized with one water molecule of crystallization. In the crystal, molecules 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) Å3 (Z = 2), which is about 108.16 Å3 (29.0%) greater than that of half the amount of the chemical α-L-sorbose [745.94 (2) Å3 (Z = 4)].
Ethyl L-sorboside, C8H16O6, was prepared from the rare sugar L-sorbose, C6H12O6, and crystallized. It was confirmed that ethyl L-sorboside formed α-pyranose with a 2
C
5 conformation. In the crystal, molecules are linked by O—H...O hydrogen bonds, forming a three-dimensional network. The unit-cell volume of the title ethyl α-L-sorboside is 940.63 Å3 (Z = 4), which is about 194.69 Å3 (26.1%) bigger than that of L-sorbose [745.94 Å3 (Z = 4)].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
