Abstract

The mol-ecule of the title compound, C(31)H(31)N(3)O(5)S, adopts a folded conformation, with the sulfonyl-bound phenyl ring lying over the pyrimidine ring [dihedral angle = 12.04 (6)° and centroid-centroid separation = 3.6986 (8) Å]. The pyrrolidine ring adopts a twist conformation, the dihydro-pyran ring is in a half-chair conformation and the two rings are cis-fused. The tosyl group is attached to the pyrrolidine ring in an equatorial position while the benzyl group is axially attached. The mol-ecular structure is stabilized by weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions. In the crystal, pairs of mol-ecules related by inversion symmetry are linked by C-H⋯O hydrogen bonds, forming chains propagating along the c axis which are cross-linked into a three-dimensional framework by further C-H⋯O links.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
