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...

Sumario: | 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]. |
