The structure and stereochemistry of the title compound, (3R,4R,4aS,10aR)-5-acetyl-3,4,4a,5,6,7,10,10a-octahydro-8-methoxy-7-methyl-6-oxo-2H-pyrano[3,2-g]pteridin-3,4-diyl diacetate, C17H22N4O8, is established, with cis H atoms at the A/B ring fusion. Molecules are linked by N-H ... O hydrogen bonds [N ... O 2.816 (5) Angstrom] to form infinite spirals about 2(1) screw axes.
