Abstract

In the title compound, C15H15ClN2O5S, the tetrahydrofuran ring adopts an envelope conformation with the O atom as the flap. The pyrrolidine ring adopts an envelope conformation with the chlorine-substituted C atom as the flap. In the crystal, two types of C-H center dot center dot center dot O hydrogen bonds generate R-2(2)(20) and R 4 4(26) rings, with adjacent rings running parallel to ac plane. Further C-H center dot center dot center dot O hydrogen bonds form a C(6) chain, linking the molecules in the b-axis direction.
