[(2R,3S,5R)-3-Acetoxy-5-(5-formyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-1-yl)-2,3,4,5-tetrahydrofuran-2-yl]methyl acetate

In the two independent but very similar molecules (A and B) of the title compound, C14H16N2O8, both six-membered pyrimidine rings are nearly planar [maximum deviations = 0.010 (3) Å in A and 0.028 (3) Å in B]. The five-membered furanose ring in molecule A adopts an envelope conformation, while the same ring in molecule B has a twisted conformation. In the crystal, the A molecules are linked via a pair of intermolecular N—H...O hydrogen bonds, forming dimers. Each A molecule is further linked to a B molecule via a second N—H...O hydrogen bond. There are also a number of C—H...·O interactions present, leading to the formation of a three-dimensional network
