Crystal structure of methyl 6-methoxy-11-(4-methoxyphenyl)-16-methyl-14-phenyl-8,12-dioxa-14,15-diazatetracyclo[8.7.0.0 2,7 .0 13,17 ]heptadeca-2(7),3,5,13(17),15-pentaene-10-carboxylate

In the title compound, C 30 H 28 N 2 O 6 , the pyran ring adopts a slightly distorted half-chair conformation and the pyrone ring adopts an envelope conformation, with the C atom bearing the carboxylate group as the flap. The pyrazole ring [maximum deviation = 0.002 (2) Å] forms a dihedral angle of 13.2 (1)° with the attached benzene ring. The near-planar atoms of the pyran ring and the pyrazole ring are close to coplanar, the dihedral angles between their mean planes being 6.4 (1)°. The dihedral angle between the pyrone ring and the benzene ring of the chromene unit is 10.7 (1)°. The molecular conformation is stabilized by an intramolecular C—H...O hydrogen bond, which generates an S (6) ring motif. In the crystal, C—H...O interactions generate supramolecular chains propagating in [100] and these are connected into double layers that stack along the c -axis direction by weak π–π interactions between pyrazole rings [centroid–centroid distance = 3.801 (1) Å].
