Methyl 6-(4-chlorophenyl)-2,4-dimethyl-1,3-dioxo-1,2,3,4,6,6a,7,12b-octahydrochromeno[4',3':4,5]pyrano[2,3-d]pyrimidine-6a-carboxylate

Abstract: In the title compound, C24H21ClN2O6, the two fused six-membered pyran rings adopt half-chair conformations. The dihedral angle between the pyrimidine ring and the chlorophenyl ring is 51.55 (3)°. In the crystal, molecules are linked by pairs of weak intermolecular C-H...O hydrogen bonds, forming inversion dimers. A C-H...[pi] interaction is also observed.
