Crystal structure of 4-(4-meth­oxy­phen­yl)-4′,4′-dimethyl-3- p-tolyl-3′,4′-di­hydro-1′ H,3 H-spiro­[isoxazole-5,2′-naphthalen]-1′-one

Abstract

In the title compound, C ₂₈H ₂₇NO ₃, the cyclo­hexa­none and isoxazole rings have envelope conformations, with the methyl­ene and spiro C atoms as the flaps, respectively. The mean plane of the isoxazole ring is inclined slightly to the p-tolyl ring, making a dihedral angle of 14.20 (9)°, and is nearly perpendicular to the mean plane through the tetra­lone moiety and to the meth­oxy­phenyl ring [dihedral angles = 83.41 (8) and 72.12 (9)°, respectively]. The crystal packing is stabilized mainly by van der Waals forces.
