چکیده
In the title compound, C(30)H(31)NO(6)S, the plane of the N-phthalimido group is nearly orthogonal to the least-squares plane of the sugar ring (defined by atoms C2, C3, C5 and O5 using standard glucose nomenclature), making a dihedral angle of 72.8 (1)°. The thio-ethyl group has the exo-anomeric conformation. The hy-droxy group forms an inter-molecular hydrogen bond to the O atom in the sugar ring, generating [100] chains. There are four close π-π contacts with centroid-centroid distances less than 4.0 Å, all with dihedral angles between the inter-acting π systems of only ≃ 8°, supporting energetically favourable stacking inter-actions.

In the crystal structure of the title compound, C(27)H(27)NO(5)S, the pyran-ose ring adopts a (4)C(1) chair conformation with puckering parameters Q = 0.639 (2) Å, θ = 174.11 (18) and ϕ = 256 (2)°. The presence of the 2,3-trans-oxazolidinone fixes the conformation of the pyran-ose ring. The phenyl group attached to the S atom and the benzyl group bonding to the N atom are each disordered over t...
