The molecule of the title compound, C31H31N3O5S, 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 dihydropyran 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 molecular structure is stabilized by weak C—H⋯O hydrogen bonds and C—H⋯π interactions. In the crystal, pairs of molecules 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.

To a solution of 1,3-dimethyl-pyrimidine-2,4,6-trione (1 mmol) in dry toluene (20 ml), the corresponding 2-(N-cinnamyl-N-tosylamino)acetaldehyde (1 mmol) and catalytic amount of the base ethylenediamine-N,N'-diacetate (EDDA) were added and the reaction mixture was refluxed for 12 h. After completion of reaction, the solvent was evaporated under reduced pressure and the crude product was chromatographed using a hexane-ethyl acetate (8:2 v/v) mixture to obtain the title compound. The compound was recrystallized from ethyl acetate solution by slow evaporation to yield colourless blocks of (I).
H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93–0.98 Å and Uiso(H) = 1.2–1.5(methyl) Ueq(C). The H atoms of the tosyl methyl group are disordered over two orientations and two sets of idealized positions rotated from each other by 60° were used. A rotating group model was used for the normal methyl groups.
Pyranopyrimidine derivatives exhibit antipyretic, analgesic and antiplatelet (Bruno et al., 2000), antiviral (Shamroukh et al., 2007) and antimicrobial (Bedair et al., 2000, 2001; Eid et al., 2004; Abdel Fattah et al., 2004) activities. We report here the
of the title compound, a pyranopyrimidine derivative.Bond lengths and angles are comparable with those observed in a related structure (Chinnakali et al., 2007). The pyrimidine ring is planar, with an r.m.s. deviation of fitted atoms of 0.032 Å, and atoms O4, O5, C23 and C24 deviating by 0.079 (1), -0.146 (1), 0.021 (2) and 0.142 (2) Å, respectively. The pyrrolidine ring adopts a twist conformation, with twist about the C2—C3 bond; the puckering parameters (Cremer & Pople, 1975) q2 = 0.345 (2) Å and φ = 87.2 (2)°, and asymmetry parameter (Duax et al., 1976) ΔC2[C2—C3] = 3.13 (14)°. The tosyl group is attached to the pyrrolidine ring in an equatorial position while the benzyl group is axially attached. The dihydropyran ring adopts a half-chair conformation, with atoms C2 and C5 deviating from the O3/C3/C6/C7 plane by -0.302 (2) Å and 0.427 (2) Å, respectively. The asymmetry parameter ΔC2[C2—C5] is 6.4 (2)°, and the puckering parameters Q, θ and φ are 0.478 (1) Å, 54.1 (2)° and 86.1 (2)°, respectively. The phenyl group is axially attached to the dihydropyran ring. The pyrrolidine ring is -fused to the dihydropyran ring.
The molecule is in a folded conformation, with the sulfonyl-bound phenyl ring lying over the pyrimidine ring [dihedral angle = 12.04 (6)°]. The folded conformation is stabilized by weak π-π interaction between phenyl and pyrimidine rings (centroid-to-centroid distance = 3.6986 (8) Å), C4—H4···O5 hydrogen bonds and C2—H2···π interaction involving the benzyl phenyl ring (C26—C31). The dihedral angle between the C17—C22 and C26—C31 phenyl rings is 57.50 (8)°.
Pairs of molecules related by inversion are linked into R22(10) (Bernstein et al., 1995) dimers by C24—H24B···O5 hydrogen bonds, and dimers related by inversion are linked into chains along the c axis by pairs of C22—H22···O4 hydrogen bonds which generate an R22(18) motif. The adjacent chains are cross-linked through C30—H30···O1 hydrogen bonds to form a three-dimensional framework.

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. |

Pyranopyrimidine derivatives exhibit antipyretic, analgesic and antiplatelet (Bruno et al., 2000), antiviral (Shamroukh et al., 2007) and antimicrobial (Bedair et al., 2000, 2001; Eid et al., 2004; Abdel Fattah et al., 2004) activities. We report here the crystal structure of the title compound, a pyranopyrimidine derivative.
Bond lengths and angles are comparable with those observed in a related structure (Chinnakali et al., 2007). The pyrimidine ring is planar, with an r.m.s. deviation of fitted atoms of 0.032 Å, and atoms O4, O5, C23 and C24 deviating by 0.079 (1), -0.146 (1), 0.021 (2) and 0.142 (2) Å, respectively. The pyrrolidine ring adopts a twist conformation, with twist about the C2—C3 bond; the puckering parameters (Cremer & Pople, 1975) q2 = 0.345 (2) Å and φ = 87.2 (2)°, and asymmetry parameter (Duax et al., 1976) ΔC2[C2—C3] = 3.13 (14)°. The tosyl group is attached to the pyrrolidine ring in an equatorial position while the benzyl group is axially attached. The dihydropyran ring adopts a half-chair conformation, with atoms C2 and C5 deviating from the O3/C3/C6/C7 plane by -0.302 (2) Å and 0.427 (2) Å, respectively. The asymmetry parameter ΔC2[C2—C5] is 6.4 (2)°, and the puckering parameters Q, θ and φ are 0.478 (1) Å, 54.1 (2)° and 86.1 (2)°, respectively. The phenyl group is axially attached to the dihydropyran ring. The pyrrolidine ring is cis-fused to the dihydropyran ring.
The molecule is in a folded conformation, with the sulfonyl-bound phenyl ring lying over the pyrimidine ring [dihedral angle = 12.04 (6)°]. The folded conformation is stabilized by weak π-π interaction between phenyl and pyrimidine rings (centroid-to-centroid distance = 3.6986 (8) Å), C4—H4···O5 hydrogen bonds and C2—H2···π interaction involving the benzyl phenyl ring (C26—C31). The dihedral angle between the C17—C22 and C26—C31 phenyl rings is 57.50 (8)°.
Pairs of molecules related by inversion are linked into R22(10) (Bernstein et al., 1995) dimers by C24—H24B···O5 hydrogen bonds, and dimers related by inversion are linked into chains along the c axis by pairs of C22—H22···O4 hydrogen bonds which generate an R22(18) motif. The adjacent chains are cross-linked through C30—H30···O1 hydrogen bonds to form a three-dimensional framework.
