title: Crystal structure of 1,2,3,4-di-O-methyl-ene-α-d-galacto-pyran-ose.
abstract: The title compound, C8H12O6, was synthesized by de-acetyl-ation of 6-acetyl-1,2,3,4-di-O-methyl-ene-α-d-galactose with sodium methoxide. The central part of the mol-ecule consists of a six-membered C5O pyran-ose 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 mol-ecules, generating a three-dimensional network.
