In the title mol-ecule, C(15)H(18)N(4)O(6), the fused 2,3-dihydro-furan ring has an envelope conformation and the spiro pyrimidine ring has a half-chair conformation. In the crystal, short inter-molecular O⋯C contacts of 2.835 (4) and 2.868 (4) Å between the carbonyl groups indicate the existence of electrostatic inter-actions, which link the mol-ecules into corrugated sheets parallel to the ab plane.
在标题分子C(15)H(18)N(4)O(6)中，稠合的2,3-二氢呋喃环呈信封构象，螺嘧啶环呈半椅构象。在晶体中，羰基之间短的分子间O⋯C接触距离为2.835 (4) Å和2.868 (4) Å，表明存在静电相互作用，这些相互作用将分子连接成平行于ab平面的波纹片层。
