Crystal structure of (E)-2-benzyl­idene-4-[(3-phenyl-4,5-di­hydro­isoxazol-5-yl)meth­yl]-2H-benzo[b][1,4]thia­zin-3(4H)-one

In the title compound, C(25)H(20)N(2)O(2)S, 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.
