(3S,4S,4aR,10aS)-5-Acetyl-3,4,4a,5,6,7,10,10a-octahydro-8-methoxy-7-methyl-6-oxo-2H-pyrano[3,2-g]pteridine-3,4-diyl Diacetate

The structure and stereochemistry of the title compound, C₁₇H₂₂N₄O₈, are reported. The compound is formed by the reaction of 5,6-diamino-2-methoxy-3-methylpyrimidin-4(3H)-one and L-xylose. It is the enantiomer of the compound synthesized using D-xylose and reported previously [Low et al. (1995). Acta Cryst. C51, 2141-2143]. There are no significant differences (apart from the absolute configuration) between the structure report here and that of the enantiomer reported previously.
