(Received 25 July 2008; accepted 31 July 2008; online 6 August 2008)

The crystalline form of 1-de­oxy-L-mannitol, C6H14O5, exists as an extensively hydrogen-bonded structure with each mol­ecule acting as a donor and acceptor for five hydrogen bonds. There are no unusual crystal-packing features; the absolute configuration was determined from the use of 6-de­oxy-L-mannose (L-rhamnose) as the starting material.

Comment top

The properties of 1-deoxy ketohexose sugars have been little studied. The crystal structure of 6-deoxy-L-galactitol has recently been published (Jenkinson et al., 2008) and herein we report the crystal structure of a similar deoxy polyol, 1-deoxy-L-mannitol an intermediate in the synthesis of 1-deoxy-L-fructose, 3 (Fig. 1) (Gullapalli et al., 2007).

The demand for the large scale production of rare sugars by biotechnological (Izumori, 2006; Izumori, 2002; Granstrom et al., 2004) and chemical (Beadle et al., 1992) methods is driven by the demand for alternative foodstuffs (Skytte, 2002) and D-tagatose itself is used as a low calorie sweetener (Levin, 2002; Howling & Callagan, 2000; Bertelsen et al. 1999). Rare monosaccharides themselves, however, have been found to demonstrate interesting pharmaceutical properties, for example, D-psicose (Takata et al., 2005; Menavuvu et al., 2006) and D-allose (Sui et al., 2005; Hossain et al., 2006) have significant chemotherapeutic properties and D-tagatose has been found to be an anti-hyperglycemic agent (Donner et al., 1999) and therefore potentially useful in the treatment of diabetes.

1-Deoxy-L-mannitol 2 (Fig. 2) was prepared from the reduction by catalytic hydrogenation of 6-deoxy-L-mannose 1 (L-rhamnose). The X-ray structure shows that the crystal exists as an extensively hydrogen bonded lattice with each molecule acting as a donor and an acceptor for 5 hydrogen bonds (Fig.3).

Experimental top

1-Deoxy-L-mannitol was recrystallized from methanol: m.p. 390K, [α]D20 +1.4 (c, 1.4 in H2O).

Refinement top

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

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.
