X-ray crystallography unequivocally shows that protection of the free hydroxyl group of 3,5-O-benzyl­idene-D-xylono-1,4-lactone with diphenyl­diazo­methane proceeded smoothly to give the title compound, C25H22O5, with no accompanying epimerization. Unlike the analogously protected lyxono lactone, the isomeric xylono lactone has two mol­ecules present in the asymmetric unit (Z' = 2). The 5-ring lactones adopt envelope conformations and the 6-ring ketals adopt chair conformations.

Comment top

Carbohydrates provide excellent starting materials for the synthesis of small chiral molecules (Collins & Ferrier, 1995). They are relatively inexpensive and provide an almost boundless pool of chiral building blocks (Draths et al., 1992). Much of their synthetic utility is however dependent on developing successful protecting group strategies.

Diazodiphenylmethane has been found to be a useful protecting group in the synthesis of methyl 2,3,6-tri-O-methyl-α-D-glucopyranoside and kojibiose octa-acetate (Jackson et al., 1982); monoalkylations of vicinal diols have been achieved with this reagent and other diaryldiazoalkanes with high regioselectivities (Petursson & Webber, 1982; Petursson et al., 2007; Petursson, 2003; Petursson, 2001). This is of particular interest for the protection of base sensitive sugar lactones as the reaction is carried out under neutral conditions (Best et al. 2008; Jenkinson et al. 2008).

The utility of the benzhydryl group as a protecting group in carbohydrate chemistry has here been demonstrated with the reaction of 3,5-O-benzylidene-D-xylono-1,4-lactone 1 with diphenyldiazomethane (Fig. 1). No epimerization at C2 was observed (Fig. 2).

Unlike the analogously protected lyxono lactone (Jenkinson et al., 2008), the asymmetric unit of the isomeric xylono lactone contains two crystallographically distinct molecules which are related by a pseudo 2-fold axis of symmetry. These are similar in geometry with the exception of two of the phenyl rings which sit at approximately 90° to each other (Fig. 3). When the core 20 atoms, of the carbohydrate backbone and 1 phenyl group, are mapped there is good overlap- r.m.s. deviations: posn 0.1139 Å, bond 0.0104 Å, torsion 2.5205°.

The crystal packing shows alternating layers of molecules in the ac plane (Fig. 4). The 5-ring lactones adopt envelope conformations with C2 or C102 out of the plane. The 6-ring ketals adopt chair conformations. There is no classic hydrogen-bonding.

Experimental top

The title lactone was recrystallized from a 1:1 mixture of ethyl acetate and cyclohexane: m.p. 395–397 K; [α]D23 +129.1 (c, 1.02 in CHCl3).

Refinement top

In the absence of significant anomalous scattering, Friedel pairs were merged and the absolute configuration was assigned from the starting material.

The relatively large ratio of minimum to maximum corrections applied in the multiscan process (1:1.80) reflect changes in the illuminated volume of the crystal. Changes in illuminated volume were kept to a minimum, and were taken into account (Görbitz, 1999) by the multi-scan inter-frame scaling (DENZO/SCALEPACK, Otwinowski & Minor, 1997).

The H atoms were all located in a difference map, but those attached to carbon atoms were repositioned geometrically. The H atoms were initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H in the range 0.93–0.98, O—H = 0.82 Å) and Uiso(H) (in the range 1.2–1.5 times Ueq of the parent atom), after which the positions were refined with riding constraints.
