To a solution of 4-hydroxycoumarin (1 mmol) in toluene (20 ml), the corresponding 2-(N-prenyl-N-tosylamino)acetaldehyde (1 mmol) and a catalytic amount of the base ethylenediamine-N,N'-diacetate (EDDA, 1 mmol) were added and the reaction mixture was refluxed for 12 h. After completion of the 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.
The water H atom was located in a difference map and its positional parameters were refined with a O—H distance restraint of 0.84 (2) Å. The water molecule has a fractional occupancy of 1/8, which was initially refined and later fixed. The Uiso values were set equal to 1.5Ueq of the carrier atom for methyl and water H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl groups.
Pyranocoumarins show strong activity against cancer cell lines (Kawaii et al., 2001) and exhibit monoamine oxidase inhibitory activity (Hossain et al., 1996). Antiulcer activity of some naturally occurring pyrano-coumarin has been reported (Goel et al., 1997). They also show anti-hepatitis B virus and cytotoxic activities (Su et al., 2009) and anti-TB activity (Xu et al., 2006). We report here the crystal structure of the title pyranocoumarin derivative.
In the title molecule (Fig.1), the coumarin ring system is planar with an r.m.s. deviation of 0.036 Å. The pyrrolidine ring has a twist conformation, with asymmetry parameter (Duax et al., 1976) ΔC2[N1] = ΔC2[C2—C3] = 1.7 (1)°. The tosyl group is equatorially attached to the pyrrolidine ring. The dihydropyran ring adopts a half-chair conformation, with the asymmetry parameter ΔC2[C2—C5] = 7.4 (1)°. The pyrrolidine ring is cis-fused to the dihydropyran ring. The sulfonyl group has a distorted tetrahedral geometry [O1—S1—O2 = 119.79 (6)°]. The molecule adopts a folded conformation, with the sulfonyl-bound phenyl ring and the pyran ring of the coumarin ring system being stacked over one another. The dihedral angle between the above two rings is 18.93 (2)° and their centroid-to-centroid separation is 3.7470 (7) Å. An intramolecular C4—H4A···O5 hydrogen bond is observed.
In the crystal structure, the water molecule with a fractional occupancy of 0.125 is involved in O—H···O and C—H···O hydrogen bonding with the coumarin derivative leading to the formation of a three-dimensional network (Fig.2).

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. |

Pyranocoumarins show strong activity against cancer cell lines (Kawaii et al., 2001) and exhibit monoamine oxidase inhibitory activity (Hossain et al., 1996). Antiulcer activity of some naturally occurring pyrano-coumarin has been reported (Goel et al., 1997). They also show anti-hepatitis B virus and cytotoxic activities (Su et al., 2009) and anti-TB activity (Xu et al., 2006). We report here the crystal structure of the title pyranocoumarin derivative.
In the title molecule (Fig.1), the coumarin ring system is planar with an r.m.s. deviation of 0.036 Å. The pyrrolidine ring has a twist conformation, with asymmetry parameter (Duax et al., 1976) ΔC2[N1] = ΔC2[C2—C3] = 1.7 (1)°. The tosyl group is equatorially attached to the pyrrolidine ring. The dihydropyran ring adopts a half-chair conformation, with the asymmetry parameter ΔC2[C2—C5] = 7.4 (1)°. The pyrrolidine ring is cis-fused to the dihydropyran ring. The sulfonyl group has a distorted tetrahedral geometry [O1—S1—O2 = 119.79 (6)°]. The molecule adopts a folded conformation, with the sulfonyl-bound phenyl ring and the pyran ring of the coumarin ring system being stacked over one another. The dihedral angle between the above two rings is 18.93 (2)° and their centroid-to-centroid separation is 3.7470 (7) Å. An intramolecular C4—H4A···O5 hydrogen bond is observed.
In the crystal structure, the water molecule with a fractional occupancy of 0.125 is involved in O—H···O and C—H···O hydrogen bonding with the coumarin derivative leading to the formation of a three-dimensional network (Fig.2).
