Abstract: In the title compound, C30H28Cl3NO5S, the pyrrolidine ring adopts an envelope conformation (with the N atom as the flap) and the thiazine ring is in a distorted chair conformation. The molecular structure shows three intramolecular C-H...O interactions leading to self-associated ring S(6) and two S(7) motifs. In the crystal, the molecules are linked by C-H...O and C-H...Cl interactions. Two R22(10) and one R22(16) centrosymmetrically related ring motifs are observed in the unit cell and they are connected through C(6) and C(11) chain motifs extending along the b and c axes, respectively.
