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.

摘要

标题化合物C(22)H(27)N(3)O(10)S是通过豆腐果苷（系统名称：4-甲酰基苯基-β-D-阿洛吡喃糖苷）的乙醇溶液、硫代氨基脲和乙酸反应合成的。该分子相对于C=N双键呈反式构象。吡喃环呈椅式构象。在晶体结构中，分子通过分子间N-H⋯O氢键连接成平行于b轴的链。
