[(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, C(14)H(16)N(2)O(8), 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.
