✦ Synopsis
In the title compound, C~24~H~25~N~3~O~5~S, both the pyrrolidine and dihydropyran rings adopt envelope conformations, and are cis-fused. The tosyl group is equatorially attached to the pyrrolidine ring. The glide-related molecules are linked by C—H...O hydrogen bonds, forming a C(6) chain along the c axis, and adjacent chains are cross-linked via C—H...O and C—H...π interactions, forming a two-dimensional network parallel to the bc plane.

The asymmetric unit of the title compound, C~22~H~29~N~3~O~5~S, contains two independent molecules, __A__ and __B__, which differ slightly in the orientation of the ethyl and tosyl groups with respect to the attached pyrrolidine ring, as evidenced by the relevant torsion angles. In both molecules, t
The title compound, C~22~H~29~NO~4~S, crystallizes with three independent molecules, __A__, __B__ and __C__, in the asymmetric unit. Each of the three independent molecules adopts a folded conformation, with the phenylsulfonyl group lying over the pyranocyclohexanone ring system, and with the pyrrol
## Abstract The 6‐(3‐hydroxypropylamino)‐3‐methylpyrimidine‐2,4‐dione (1) did not afford the expected 6‐(3‐chloro‐propylamino)‐ derivative on reaction with thionyl chloride, but, instead, the pyrimidine rings were joined __via__ a sulfur bridge to give 9,9′‐thiobis(1,2,3,4,7,8‐hexahydro‐7‐melnyl‐6_
