Deskripsi
The title compound, C34H32O6S, is an ido-configured thioglycoside 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 molecules packing into a three-dimensional network via C—H...O and three C—H...π interactions. The former interactions, occuring between molecules related by a twofold axis, define an R22(26) motif.
