Abstract: In the crystal structure of the title compound, C₂₇H₂₇NO₅S, the pyranose ring adopts a ⁴C₁ chair conformation with puckering parameters Q = 0.639 (2) Å, = 174.11 (18) and = 256 (2)°. The presence of the 2,3-trans-oxazolidinone fixes the conformation of the pyranose ring. The phenyl group attached to the S atom and the benzyl group bonding to the N atom are each disordered over two positions with site occupancies of 0.624 (3):0.376 (3) and 0.526 (3):0.474 (3), respectively. An intermolecular O-HO hydrogen bond is observed.
