Two routes for the synthesis of the amidine-linked pseudo-disaccharide were developed. The amidine linkage was constructed by the intermolecular or intramolecular coupling between thioamide and amine in the presence of mercury (II) chloride. The former construction from d-arabinono-1,5-thiolactam and 6-amino-6-deoxy-d-glucoside gave the corresponding pseudo-disaccharide. The latter construction of
开发了两种方法合成the连接的假二糖。通过在氯化汞(II)存在下硫酰胺和胺之间的分子间或分子内偶联来构建am键。d-阿拉伯糖基-1,5-硫代内酰胺和6-氨基-6-脱氧-d-葡萄糖苷的前一种结构给出了相应的假二糖。在4-(5-氨基-5-脱氧-d-硫代阿拉伯氨酰基)氨基-4-脱氧-d-葡糖苷的情况下证明了linkage键的后一种结构。
