RESUMO
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-Hâ¯O hydrogen bonds, forming a three-dimensional network. The unit-cell volume of the title compound, methyl l-sorboside monohydrate, is 481.13â (2)â Å3 (Z = 2), which is about 108.16â Å3 (29.0%) greater than that of half the amount of the chemical α-l-sorbose [745.94â (2)â Å3 (Z = 4)].
RESUMO
Ethyl l-sorboside, C8H16O6, was prepared from the rare sugar l-sorbose, C6H12O6, and crystallized. It was confirmed that ethyl l-sorboside formed α-pyran-ose with a 2 C 5 conformation. In the crystal, mol-ecules are linked by O-Hâ¯O hydrogen bonds, forming a three-dimensional network. The unit-cell volume of the title ethyl α-l-sorboside is 940.63â Å3 (Z = 4), which is about 194.69â Å3 (26.1%) bigger than that of l-sorbose [745.94â Å3 (Z = 4)].
