3,4-O-Isopropyl­idene-2,7-di-O-p-tolyl­sulfonyl-α-l-xylo-3-heptulo-3,6-furan­osononitrile

In the title compound, C(24)H(27)NO(10)S(2), derived from l-sorbofuran­ose, the fused five-membered rings display envelope conformations. The two tosyl­ate branches are in equatorial positions with respect to the furan­ose ring, while the hydr­oxy group is in the axial position. In the crystal structure, the hydr­oxy group is involved in inter­molecular O—H⋯O hydrogen bonds, linking mol­ecules in chains along [100].
