Experimental Crystal data

R factor = 0.036; wR factor = 0.110; data-to-parameter ratio = 15.1. In the title compound, C14H13ClN2O5S, the chlorine-substi-tuted tetrahydrofuran ring adopts a twist conformation and the other tetrahydrofuran ring an envelope conformation with the O atom as the flap. The pyrrolidine ring adopts a twist conformation. In the crystal, C—H O hydrogen bonds link the molecules into zigzag chains running along the b-axis direction. Related literatur
