Abstract:
The title compound, C15H17NO4, is the exo isomer with a syn arrangement of the O atom in the isoxazole ring to the methyl group of the bicyclic alkene. The dihedral angle between the isoxazole ring and the benzene ring is 7.42 (9)°. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules, forming a three-dimensional network. The isoxazole O atom is an acceptor for both weak hydrogen bonds.
