【 摘 要 】

In the title compound, C19H18FNO3S, the five-membered oxazolidine ring adopts an envelope conformation with the methine C atom of the fused bond as the flap. Its mean plane is oriented at a dihedral angle of 50.38 (1)° with respect to the fluoro­phenyl ring. The six-membered thio­pyran ring has a half-chair conformation and its mean plane is almost coplanar with the fused benzene ring, making a dihedral angle of 4.94 (10)°. The two aromatic rings are inclined to one another by 85.96 (11)°, and the mean planes of the oxazolidine and thio­pyran rings are inclined to one another by 57.64 (12)°. In the crystal, mol­ecules are linked by C—H⋯π inter­actions, forming a three-dimensional structure.
