Abstract

The title compound, C(34)H(32)O(6)S, is an ido-configured thio-glycoside building block for heparan sulfate fragments. It contains disordered tolyl and O-benzyl groups with occupancy ratios of 0.539 (13):0.461 (13) and 0.613 (13):0.387 (13), respectively, as determined from a weakly diffracting crystal. The fused rings adopt chair conformations with the mol-ecules packing into a three-dimensional network via C-H⋯O and three C-H⋯π inter-actions. The former inter-actions, occuring between mol-ecules related by a twofold axis, define an R(2) (2)(26) motif.
