โฆ Synopsis
In the chiral title compound, C 33 H 42 N 4 O 2 S 2 , the dihedral angle between the imidazole ring planes is 79.47 (17) . The packing is consolidated by van der Waals forces and weak C-Hร ร รS interactions.

In the chiral title compound, C 39 H 58 N 4 O 2 S 2 , the complete molecule is generated by crystallographic twofold symmetry, with one C atom lying on the rotation axis. The packing is established by van der Waals forces.
The relative stereochemistry of the title compound, C~16~H~22~N~4~O~2~, a key intermediate in the synthesis of 3-deoxy imino sugars, was firmly established by X-ray crystallographic analysis. The absolute configuration was inferred from the starting material, D-galactose. There are no unusual crysta
