【 摘 要 】

In the title compound, C25H20N2O2S, the di­hydro­isoxazole ring exhibits an envelope conformation with the methine atom being the flap, while the 1,4-thia­zine ring displays a screw-boat conformation. The six-membered ring fused to the 1,4-thia­zine ring makes dihedral angles of 63.04 (2) and 54.7 (2)° with the mean planes through the five-membered heterocycle and the attached phenyl ring, respectively. The phenyl group connected to the 1,4-thia­zine ring is disordered over two sites [major component = 0.57 (2)]. The most prominent inter­actions in the crystal structure are C—H⋯O hydrogen bonds that link mol­ecules, forming inversion dimers, and C—H⋯N hydrogen bonds that link the dimers into columns parallel to the b axis.
