چکیده
In the title compound, C(17)H(17)NO(3), the five-membered isoxazoline ring adopts an envelope conformation with the chiral C atom at the flap position and 0.133 (2) Å out of the mean plane formed by the other four atoms. The two benzene rings form dihedral angles of 6.05 (5) and 81.52 (5)° with the C-C-N-O plane of the isoxazoline ring. The crystal structure is stabilized by weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
