Abstract

The title compound, C8H12O6, was synthesized by deacetylation of 6-acetyl-1,2,3,4-di-O-methylene-α-D-galactose with sodium methoxide. The central part of the molecule consists of a six-membered C5O pyranose ring with a twist-boat conformation. Both fused dioxolane rings adopt an envelope conformation with C and O atoms as the flap. In the crystal, O—H...O and C—H...O hydrogen bonds are present between adjacent molecules, generating a three-dimensional network.
