| Popis: | In the title molecule, C15H18N4O6, the fused 2,3-dihydrofuran ring has an envelope conformation and the spiro pyrimidine ring has a half-chair conformation. In the crystal, short intermolecular O...C contacts of 2.835 (4) and 2.868 (4) Å between the carbonyl groups indicate the existence of electrostatic interactions, which link the molecules into corrugated sheets parallel to the ab plane. |
