Abstract: The title compound, C22H27N3O10S, was synthesized by reaction of an ethanol solution of helicid (systematic name: 4-formylphenl--D-allopyranoside), thiosemicarbazide and acetic acid. The molecule exhibits a trans conformation with respect to the C=N double bond. The pyran ring adopts a chair conformation. In the crystal structure, the molecules are linked into chains parallel to the b axis by intermolecular N-H
O hydrogen bonds.
