description In the title mol­ecule, C(15)H(18)N(4)O(6), 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.
