In the title compound, C21H22Cl2O4, 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 molecules along [100]. The structure is further consolidated by weak C—H⋯O, C—H⋯Cl and C—H⋯π interactions. The absolute structure was determined.
