Abstract
The structure and stereochemistry of the title compound, y-7-methyl-6- oxo-2H-pyrano[3,2-g]pteridin-3,4-diyl diacetate, C17H22N4O8, is establ ished, with cis H atoms at the A/B ring fusion. Molecules are linked b y N-H ... O hydrogen bonds [N ... O 2.816 (5) Angstrom] to form infini te spirals about 2(1) screw axes.
