蔗糖化学─—三糖和四糖合成的研究
Sucrose Chemistry :Studies on the Synthesis of Tri- and Tetra-Saccharides
【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,CaH_2-苯,硝基甲烷(1:1)或Ag_2CO_3,CaH_2-二氯甲烷]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。
【Abstract】 Condensation of sucrose acetate with acetylglycosyl bromides in 1 : 1 benzene-nitromethane in presence of mercuric cyanide ,calcium hydride or indichloromethane 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.
