1,1′,3,3′,5,5′-Hexamethylspiro[furo[2,3-d]pyrimidine-6(5H),5′-pyrimidine]-2,2′,4,4′,6′(1H,3H,1′H,3′H,5′H)-pentaone
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...
