Methyl 6-eth­oxy-3-phenyl-3a,4-dihydro-3H-chromeno[4,3-c]isoxazole-3a-car­boxylate

In the title compound, C(20)H(19)NO(5), the dihedral angle between the mean plane of the pyran ring (which has a half-chair conformation) and the benzene ring of the chromeno ring system is 7.21 (7)°. The dihedral angle between the mean plane of the chromeno ring system and the isoxazole ring is 21.78 (6)°, while the isoxazole ring forms a dihedral angle of 72.60 (8)° with the attached phenyl ring. In the crystal, mol­ecules are linked via pairs of C—H⋯O hydrogen bonds, forming inversion dimers with an R (2) (2)(10) ring motif. These dimers are linked via C—H⋯N hydrogen bonds, forming chains along [001].
