In the title compound, C(22)H(29)N(3)O(5)S, the pyrrolidine ring is cis-fused to the dihydro-pyran ring. The pyrrolidine and dihydro-pyran rings adopt twist and half-chair conformations, respectively. The mol-ecule is in a folded conformation; the sulfonyl-bound benzene ring lies over the pyrimidine-dione ring, with a weak π-π inter-action [centroid-centroid distance = 3.6147 (4) Å]. A weak intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked into a three-dimensional network by C-H⋯O hydrogen bonds.
在标题化合物C₂₂H₂₉N₃O₅S中，吡咯烷环与二氢吡喃环顺式稠合。吡咯烷环和二氢吡喃环分别采取扭曲构象和半椅式构象。分子呈折叠构象；磺酰基连接的苯环位于嘧啶二酮环上方，存在弱的π-π相互作用[质心-质心距离 = 3.6147 (4) Å]。一个弱的分子内C-H⋯O氢键形成了一个S(6)环模式。在晶体中，分子通过C-H⋯O氢键连接成三维网络。
