Crystal structure of (R)-5-[(R)-3-(4-chloro­phen­yl)-5-methyl-4,5-di­hydro­isoxazol-5-yl]-2-methyl­cyclo­hex-2-enone

The title compound, C(17)H(18)ClNO(2), was prepared and isolated as a pure diastereoisomer, using column chromatography followed by a succession of fractional crystallizations. Its exact structure was fully identified via (1)H NMR and confirmed by X-ray diffraction. It is built up from a central five-membered di­hydro­isoxazole ring to which a p-chloro­phenyl group and a cyclo­hex-2-enone ring are attached in the 3 and 5 positions. The cyclo­hex-2-one and isoxazoline rings each exhibit an envelope conformation. The crystal packing features C—H⋯O, C—H⋯N and C—H⋯π inter­actions, which generate a three-dimensional network.
