1-[4-(2,3,4,6-Tetra-O-acetyl-?-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-?-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.

[2-(Benzyl-idene-amino)-4,5,6,7-tetra-hydro-benzo[b]thio-phen-3-yl](phen-yl)methanone.

Project description:In the title compound, C22H19NOS, the cyclo-hexene ring of the tetra-hydro-benzo-thio-phenyl ring system adopts a slightly distorted half-chair conformation and is twisted slightly [7.5?(8)° for the major disorder component] from the mean plane of the thio-phene ring.
