Methyl 1-phenyl-3-p-tolyl-1,9b-dihydro-3H-chromeno[4,3-c]isoxazole-3a(4H)-carboxylate
In the title compound, C25H23NO4, the pyran ring of the chroman moiety has an envelope conformation with the methylene C atom as the flap. The isoxazole ring has a twist conformation on the O—C bond. The dihedral angle between their mean planes is 57.87 (9)°. The attached phenyl and benzene rings ar...

| Summary: | In the title compound, C25H23NO4, the pyran ring of the chroman moiety has an envelope conformation with the methylene C atom as the flap. The isoxazole ring has a twist conformation on the O—C bond. The dihedral angle between their mean planes is 57.87 (9)°. The attached phenyl and benzene rings are twisted away from its mean plane by 56.19 (10) and 50.57 (10)°, respectively. These two rings are normal to each other, subtending a dihedral angle of 89.2 (1)°. In the crystal, there are no classical hydrogen bonds; the molecules are linked via C—H...π interactions, forming a two-dimensional network lying parallel to (10-1). |
