Intermolecular O—H O and weak C—H O hydrogen bonding helps to stabilize the crystal structure of the title compound, C11H13NO5.

Comment

Optically active polyhydroxy compounds are very useful intermediates in asymmetric organic syntheses. We have recently reported the crystal structures of some reagents for the synthesis of polyhydroxy compounds (Heet al., 2006). The title compound, (I), is an important synthetic building block for optically active 1,3,5-triols (Chen et al., 1987). We report here the crystal structure of (I).

The molecular structure of (I) is shown in Fig. 1. Bond lengths and angles in (I) are normal. The O1-hydroxy group forms bifurcated hydrogen bonds (Table 1). Intermolecular O—H O and weak C—H O hydrogen bonding helps to stabilize the crystal structure.

Experimental

To a solution of 3-nitrobenzaldehyde (75.5 mg, 0.5 mmol) and (S)-N -phenylpyrrolidine-2-carboxamide (19 mg, 20 mmol) in a mixture of water (1 ml) and THF (1 ml) was added 4-hydroxybutan-2-one (0.5 ml). The mixture was stirred at 273 K for 5 d. It was then treated with saturated ammonium chloride solution. The aqueous layer was extracted with ethyl acetate and dried over anhydrous magnesium sulfate. The solvent was removed and the residue was purified by column chromatography on silica gel (eluant: hexane–ethyl acetate 1:1). Colourless single crystals of (I) were obtained by recrystalliza-tion from an ethanol solurecrystalliza-tion.

Carbon-bound H atom were positioned geometrically (C—H = 0.95–1.00 A˚ ) and allowed to ride on the parent C atoms, withUiso(H)

= 1.2Ueq(C). Hydroxy H atoms were located in a difference Fourier

map and refined isotropically. In the absence of significant anomalous scattering effects, Friedel pairs were merged; the absolute config-uration of (I) was not determined, and is assigned here arbitrarily.

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.
