Abstract: The title compound, C₃₀H₂₅NO₂S, contains an isoxazolidine ring in a twist conformation with the spiro-C [0.404  (2)  Å] and the adjacent C atom [0.266  (2)  Å] deviating from the plane of the remaining three atoms. The thiapyran ring adopts a sofa conformation, with the five C atoms in a common plane (r.m.s.d. = 0.033  Å) and the S atom deviating by 0.984  (2)  Å from this plane.
