Crystal structure of 1,2,3,5-di-O-methyl-ene-α-d-xylo-furan-ose.

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.
