The anomeric hydroxyl of lactose was carbamoylated selectively by treating the free sugar with alkylisocyanates, thus without preliminary protection of the other hydroxyls of the lactose molecule. Moreover, the readily available 1-aminolactose and 1-octyl-aminolactose reacted with isocyanates and isothiocyanates to afford selectively -lactosyl -alkylureas and -lactosyl -alkylthioureas, respectively
通过用烷基异氰酸酯处理游离糖来选择性地将乳糖的异头羟基氨基甲酸酯化,因此没有初步保护乳糖分子的其他羟基。另外,容易获得的1-aminolactose和1-辛基aminolactose与异氰酸酯和异硫氰酸酯反应,以选择性得到乳糖苷神经-alkylureas和乳糖苷神经分别-alkylthioureas。
