Ethyl 3-(4-chloro­benzo­yl)-1-(4-chloro­benz­yl)-4-(4-chloro­phen­yl)-2,2-dioxo-3,4,6,7,8,8a-hexa­hydro-1H-pyrrolo­[2,1-c][1,4]thia­zine-1-carboxyl­ate

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.
