1,2:5,6-di-O-isopropylidene-α-D-glucofuranose (2 mmol, 0.520 g) was added to the mixture of powdered K2CO3 (10 mmol, 1.382 g), tetrabutylammonium bromide (2 mmol, 0.645 g) and acetonitrile (20 ml). The mixture was stirred for 20 minutes, then the chiral synthon 5-(R)-(l-menthyloxy)-2(5H)-furanone (4 mmol, 0.953 g) was added and the mixture was stirred at room temperature for 8 days until TLC analysis indicated that the chiral synthon had been completely consumed. After the addition of acetonitrile (50 ml), the mixture was filtered and the salts were washed with acetonitrile. The organic layer was dried over MgSO4, evaporated, and purified by to give a white solid, which was recrystalized to afford colorless crystal.

All H atoms were geometrically positioned (C—H 0.93-0.98 Å) and refined as riding, with Uiso(H) = 1.2-1.5 Ueq(C). In the absence of any significant anomalous scatterers in the molecule, the 2428 Friedel pairs were merged before the final refinement.

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 F > 2 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 well known chiral 5-(R)-(l-menthyloxy)-2(5H)-furanone behaves as a Michael acceptor towards carbon, oxygen, sulfur and nitrogen nucleophiles to afford chiral 4-(R)-(l-menthyloxy)-3-substituted-butyrolactone (Huang et al., 1999; Wang et al., 1999; Fu et al., 2003; Yu et al., 2008). Recently, when we have used 1,2:5,6-di-O-isopropylidene-D-glucofuranose as Michael donor to react with 5-(R)-(l-menthyloxy)-2(5H)-furanone, the adduct was not yielded, but the title compound, (I) - unexpected product of the self-addition of 5-(R)-(l-menthyloxy)-2(5H)-furanone - was obtained. Herein, we report the synthesis, characterization and crystal structure of (I) (Fig. 1).
In the crystal structure, each molecule is connected by six adjacent molecules through weak intermolecular C—H···O hydrogen bonds (Table 1) between H atoms of menthyloxy groups, or H atoms of lactone, and O atoms of the carbonyl groups, leading to the formation of a two-dimensional sheet parallel to (a+c)b plane (Fig. 2). The layers are further packed through van der Waals forces..
The absolute configuration of the title compound was established on the basis of the chiral l-menthyloxy group. In the addition reaction, the three chiral centers on the l-menthyloxy group did not change because they did not participant in the reaction. Accordingly, the stereogenic center of C7 is determined as R, the configuration of C4 and C8 are retained.
