cis-1-Ethyl-4,4,6,8-tetramethyl-2-tosyl-2,3,3a,4,6,7,8,9-octahydro-1H-pyrrolo[3′,4′:3,4]pyrano[6,5-d]pyrimidine-7,9-dione
摘要：
In the title compound, C22H29N3O5S, the pyrrolidine ring is cis-fused to the dihydropyran ring. The pyrrolidine and dihydropyran rings adopt twist and half-chair conformations, respectively. The molecule is in a folded conformation; the sulfonyl-bound benzene ring lies over the pyrimidinedione ring, with a weak π–π interaction [centroid–centroid distance = 3.6147(4)]. A weak intramolecular C—HO hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked into a three-dimensional network by C—HO hydrogen bonds.
