, was synthesized by a cross-metathesis reaction.
The dihedral angle between the aromatic ring and the butenol side chain is
30.2 (2). In the crystal, inversion dimers are formed through O—HO
hydrogen bonds and these are linked into chains by additional O—HO
contacts. These chains are linked into sheets in the bc plane by C—HO
hydrogen bonds.
Structure description
The title compound (Fig. 1) was synthesized by the cross-metathesis (Scholl, et al. 1999) of
eugenol and cis-2-butene-1,4-diol, as previously described (Taber & Frankowski, 2006).
This compound is a natural product that can also be isolated from the rhizomes of
Zingiber cassumunar (Masuda & Jitoe, 1995).
The dihedral angle between the aromatic ring and the butenol side chain is 30.2 (2).
The methyl group of the methoxy-substituent is twisted out of the plane of the aromatic
ring by 6.8 (2). In the crystal, the unit cell contains inversion dimers connected by
hydrogen bonding. Each phenol hydroxyl group acts as a hydrogen-bond donor to the
allylic hydroxyl in its dimeric counterpart through O1—H1O2 hydrogen bonds
(Table 1 and Fig. 2). The allylic hydroxyl group is a bifurcated donor, forming O2—
H2O1 and O2—H2O3 hydrogen bonds that link the dimers into supramolecular
chains propagated along the c-axis direction. Chains of dimers are linked by C7–H7O3
hydrogen bonds forming sheets of molecules in the bc plane

phenyl)-4,5-dihydroimidazol-2-ylidene][benzylidene]ruthenium(IV) dichloride (Grubbs,
2004), was used to facilitate the cross metathesis of eugenol with cis-1,4-butenediol, to

Special details
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.
