Tiritiris I, Tussetschläger S, Kantlehner W - Acta Crystallogr E Crystallogr Commun (2015)

Bottom Line: The title compound, C7H10O5, was synthesized by reaction of d-xylose with paraformaldehyde.The protected O atoms of both cyclic acetal groups are oriented so that the four chiral C atoms of the furan-ose part show an R configuration.C-H⋯O hydrogen bonds are present between adjacent mol-ecules, generating a three-dimensional network.

ABSTRACT
The title compound, C7H10O5, was synthesized by reaction of d-xylose with paraformaldehyde. In the crystal, the central part of the mol-ecule consists of a five-membered C4O ring with an envelope conformation, with the methine C atom adjacent to the O atom being the flap. The protected O atoms of both cyclic acetal groups are oriented so that the four chiral C atoms of the furan-ose part show an R configuration. C-H⋯O hydrogen bonds are present between adjacent mol-ecules, generating a three-dimensional network.
