1,5-Anhydro-3,6-di-O-benzyl-2-de-oxy-1,2-C-dichloro-methyl-ene-d-glycero-d-gulo-hexitol.
In the title compound, C(21)H(22)Cl(2)O(4), the pyranosyl ring adopts a twist-boat conformation with the O-benzyl groups in equatorial positions. In the crystal, O-H⋯O hydrogen bonding results in infinite chains of mol-ecules along [100]. The structure is further consolidated by weak C-H⋯O, C-H⋯Cl and C-H⋯π inter-actions. The absolute structure was determined.
