In the title compound, C19H19NO13, one of the two fused furanose rings adopts an whereas the other displays a twisted conformation. The is stabilized by intermolecular C—H⋯π interactions between a methine H atom and the triacetoxyphenyl ring of an adjacent molecule, and by weak non-classical intermolecular C—H⋯O hydrogen bonds.

3,4,5-triacetoxybenzoic acid(2.96 g, 10 mmol), Isosorbide Mononitrate (1.91 g, 10 mmol, CAS No:16051–77-7, [α]D=168 ° (c=1.0, EtOH) and DMAP (0.24 g, 1 mmol) were dissolved in 100 ml dry THF, then DCC (4.12 g, 10 mmol) was added to the solution at 0°C. The mixture was stirred at room temperature for 5 h. The resulting mixture was filtered and concentrated in vacuo. The crude product was purified by over silica gelusing ethyl acetate/n-hexane (7:3) as Yield: 4.21 g (85%). Single crystals of the title compound suitable for X-ray diffraction was recrystallized from hexane/ethyl acetate (1:1).
All H atoms were positioned geometrically and treated as riding with aromatic C—H = 0.93 Å, methine C—H = 0.98 Å, methylene C—H = 0.97Å & methyl C—H = 0.96 Å. The H atom isotropic displacement parameters were fixed; Uiso(aromatic H, methine H) = 1.2 times Ueq of the parent atom; Uiso(methylene H, methyl H) = 1.5 times Ueq of the parent atom.
In the absence of significant
the could not be reliably determined and then the Friedel pairs were merged and any references to the were removed. The has been assigned by reference to unchanging chiral centres in the synthetic procedure.The title compound is synthesized by esterification of 3,4,5-triacetoxybenzoic acid with Isosorbide Mononitrate.It can be rapidly metabolized to 3,4,5-trihydroxybenzoic acid and Isosorbide Mononitrate in vivo(Carini et al.,2002). 3,4,5-trihydroxybenzoic acid is a bioactivesubstance which can scavenge oxygen free radicals and Isosorbide Mononitrate is a classical nitric oxide-donor drug. This bifunctional molecule may have better bioactivity but do bring fewer side effect.
The molecule is built up from the isosorbide mononitrate skeleton substituted on C4 by the 3,4,5-triacetoxybenzoate (Fig. 1). The two fused furanose rings have slightly different conformation. Indeed, the Cremer & Pople (1975) puckering parameters for the C1-O2-C3-C4-C5 ring are Q(2) = 0.359 (4)Å and φ(2) = 289.1 (6)° whereas those for the C5-O6-C7-C8-C1 ring are Q(2) = 0.334 (4)Å and φ(2) = 343.4 (7)°. These values indicate that these two rings have different extent of puckering caused by the different substituent group in the ring. The pseudorotation parameters (Rao et al. 1981) for C1-O2-C3-C4-C5 ring are P = 20.8 (4)° & τ(M) = 37.3 (2)° for the C5—C4 reference bond with the closest pucker descriptor being enveloped on C(4) and those for C5-O6-C7-C8-C1 ring are P = 75.4 (4)° and τ(M) = 35.7 (3)° for the C8—C1 reference bond with the closest puckering descriptor being twisted on C5—O6.
Owing to the know
of the starting isosorbide mononitrate, the of the title compound could be deduced to be 1S,4S,5S,8R.The molecular packing is stabilized by weak non-classical intermolecular C–H···O hydrogen bonds and by intermolecular C–H···π interaction between methine H atom of perhydrofurofuranyl system and the triacetoxyphenyl ring of an adjacent molecule (Table 1, Cg1 is the centroid of C42—C47 phenyl ring).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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. |

The title compound is synthesized by esterification of 3,4,5-triacetoxybenzoic acid with Isosorbide Mononitrate.It can be rapidly metabolized to 3,4,5-trihydroxybenzoic acid and Isosorbide Mononitrate in vivo(Carini et al.,2002). 3,4,5-trihydroxybenzoic acid is a bioactivesubstance which can scavenge oxygen free radicals and Isosorbide Mononitrate is a classical nitric oxide-donor drug. This bifunctional molecule may have better bioactivity but do bring fewer side effect.
The molecule is built up from the isosorbide mononitrate skeleton substituted on C4 by the 3,4,5-triacetoxybenzoate (Fig. 1). The two fused furanose rings have slightly different conformation. Indeed, the Cremer & Pople (1975) puckering parameters for the C1-O2-C3-C4-C5 ring are Q(2) = 0.359 (4)Å and φ(2) = 289.1 (6)° whereas those for the C5-O6-C7-C8-C1 ring are Q(2) = 0.334 (4)Å and φ(2) = 343.4 (7)°. These values indicate that these two rings have different extent of puckering caused by the different substituent group in the ring. The pseudorotation parameters (Rao et al. 1981) for C1-O2-C3-C4-C5 ring are P = 20.8 (4)° & τ(M) = 37.3 (2)° for the C5—C4 reference bond with the closest pucker descriptor being enveloped on C(4) and those for C5-O6-C7-C8-C1 ring are P = 75.4 (4)° and τ(M) = 35.7 (3)° for the C8—C1 reference bond with the closest puckering descriptor being twisted on C5—O6.
Owing to the know absolute configuration of the starting isosorbide mononitrate, the absolute configuration of the title compound could be deduced to be 1S,4S,5S,8R.
The molecular packing is stabilized by weak non-classical intermolecular C–H···O hydrogen bonds and by intermolecular C–H···π interaction between methine H atom of perhydrofurofuranyl system and the triacetoxyphenyl ring of an adjacent molecule (Table 1, Cg1 is the centroid of C42—C47 phenyl ring).
