1-[4-(2,3,4,6-Tetra-O-acetyl-β-d-allo-pyranos-yloxy)benzyl-idene]thio-semi-carbazide.

ABSTRACT: The title compound, C(22)H(27)N(3)O(10)S, was synthesized by reaction of an ethanol solution of helicid (systematic name: 4-formylphenl-β-d-allopyranoside), thio-semicarbazide and acetic acid. The mol-ecule exhibits a trans conformation with respect to the C=N double bond. The pyran ring adopts a chair conformation. In the crystal structure, the mol-ecules are linked into chains parallel to the b axis by inter-molecular N-H⋯O hydrogen bonds.

(E)-2-(4-Benz-yloxy-2-hy-droxy-benzyl-idene)-N-methyl-hydrazinecarbo-thio-amide.

Project description:The mol-ecule of the title compound, C16H17N3O2S, adopts an E conformation with respect to the azomethine C=N bond. The hydrazinecarbo-thio-amide fragment is close to planar, with a largest deviation from the least-squares plane of 0.079 (2) Å for the hydrazide N atom. This fragment forms a dihedral angle of 9.43 (9)° with the central benzene ring. The benzene rings are inclined to one another by 67.55 (12)°. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond involving the azomethine N atom. In the crystal, mol-ecules are linked through weak N-H⋯S and N-H⋯O hydrogen bonds into double ribbons along [010]. The crystal packing also features C-H⋯π inter-actions.
