چکیده
In the title compound, C(26)H(31)NO(6)S, the five-membered pyrrolidine ring adopts an envelope conformation and the six-membered thia-zine ring is in a distorted chair conformation. The crystal packing is stabilized through an inter-molecular C-H⋯O inter-action, generating inversion-related R(2) (2)(10) ring motifs.

In the title compound, C30H28Cl3NO5S, the pyrrolidine ring adopts an envelope conformation (with the N atom as the flap) and the thia-zine ring is in a distorted chair conformation. The mol-ecular structure shows three intra-molecular C-H⋯O inter-actions 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 inter-actions. Two R 2 ...
