While the 26H38O15, a synthetic derivative of sucrose, was originally reported 40 years ago [Drew et al. (1979). Carbohydr. Res. 71, 35–42], the present work has allowed for the determination of its through the application of techniques.

Structure description
Sucrose and certain derivatives are profoundly important commodity chemicals in, for example, the food, nutraceutical, cosmetic, dental and pharmaceutical industries (Farrán et al., 2015). However, selective manipulation of the eight distinct hydroxyl groups within the parent compound is challenging (Queneau et al., 2008). Accordingly, we were attracted to the title derivative, a previously reported compound (Fanton et al., 1981; Khan & Mufti, 1975; Poschalko et al., 2003), as a readily accessible one that could serve as the starting point for selective re-functionalization of the sucrose framework and so affording a range of single-compound derivatives. To such ends we required detailed structural information on the title compound, including its solid-state properties [so as to inform proposed mechanochemical studies (Achar et al., 2017)] and thus undertook the high-resolution single-crystal X-ray analysis reported here (Fig. 1). The compound crystallized in the chiral monoclinic P21. The was determined by Upon of the this calculated to the unambiguous value of 0.05 (8).
A single-crystal, room-temperature X-ray analysis of the title compound was reported nearly forty years ago (Drew et al., 1979) but its was not determined by that means. For the purposes of the present study, a sample of this sucrose derivative was prepared by the same means as used earlier (Drew et al., 1979), involving initial diacetonide formation followed by acetylation of the four remaining free hydroxyl groups (Khan & Mufti, 1975). Crystals suitable for analysis were grown, using vapour-diffusion techniques, from diethyl ether/40–60 petroleum spirits and the derived spectroscopic data matched those reported previously. The R factor arising from the present study at 150 K was superior to that obtained earlier (3.66% versus 5.5%) and this is mirrored through the more accurate unit-cell parameters. As noted in the earlier study (Drew et al., 1979), the eight-membered and trioxygenated ring embedded within this sucrose derivative is an unusual structural feature, as is the conformation of the tetrahydrofuranyl residue wherein the ring oxygen atom (O2′) is exo-related to C6′. There are a number of intramolecular C—H⋯O contacts present (Table 1).
In the crystal, molecules are linked by a number of C—H⋯O hydrogen bonds, forming slabs parallel to the ab plane (Table 1 and Fig. 2).
Synthesis and crystallization
Following a literature procedure (Khan and Mufti), 2,2-dimethoxypropane (25.0 ml, 204 mmol) was added, in one portion, to a magnetically stirred solution of sucrose (4.96 g, 14.5 mmol) and p-toluenesulfonic acid (514 mg, 3.00 mmol) in dimethylformamide (DMF, 250 ml) maintained at 295 K. The ensuing mixture was left to stir for 24 h before being treated with sodium bicarbonate (5 ml of a saturated aqueous solution) and the DMF then removed by distillation under reduced pressure (323 K at 15 mm Hg). The yellow gum thus obtained was dissolved in pyridine (80 ml) and the solution so formed treated, in one portion, with acetic anhydride (35.0 ml, 317 mmol). The reaction mixture was stirred at 295 K for 24 h then concentrated by removal of the pyridine through co-distillation with toluene and so leaving a golden-coloured residue. This residue was subjected to flash (silica, 1:1 v/v ethyl acetate/40–60 petroleum spirits elution) and concentration of the relevant fractions (Rf = 0.3 in 2:3 v/v ethyl acetate/40–60 petroleum spirits) afforded the title compound (878 mg, 10%) as colourless needles. A small sample of this material was recrystallized by vapour diffusion (using diethyl ether and 40–60 petroleum spirits) to afford single crystals suitable for X-ray m.p. 406-408 K [lit. (Fanton et al., 1981) m.p. 409–410 K], [α]D +10.3 (c = 1.0, chloroform) {lit. (Fanton et al., 1981) [α]D +13 (c = 1, chloroform)}.
