Abstract

Abstract: Condensation of sucrose acetate with acetylglycosyl bromides in 1:1 benzene-nitromethane in presence of mercuric cyanide,calcium hydride or in dichloromethane in presence of silver carbonate, calcium hydride gave Tri- and Tetra-Saccharides containing sucrose molecule. The configuration of oligosaccharide linkage was clearly shown by ¹H NMR data.

Key words: sucrose acetate, acetylglycosyl bromide, tri- and tetra-saccharide containing sucrose molecule

摘要： 将蔗糖乙酸酯和乙酰基糖的溴化物在两种催化体系[Hg(CN)₂，CaH₂-苯，硝基甲烷（1:1）或Ag₂CO₃，CaH₂-二氯甲烷]中进行缩合反应，得到了以蔗糖分子为母体的三糖和四糖化合物。其¹HNMR数据显示出糖苷键的构型。

关键词: 蔗糖乙酸酯, 乙酰基糖的溴化物, 含有蔗糖分子的三糖, 四糖
