    • Azidohalogenobenzyl derivatives of the formula (I) ##STR1## wherein A is a halogen atom, B is a halogen atom or a hydrogen atom, and X is a group reactive with a hydroxy group, methods of protecting hydroxy group(s) using said derivatives, and sugar compounds wherein a hydrogen atom of at least one hydroxy group is substituted by an azidohalogenobenzyl group. According to the present invention, there are provided novel derivatives capable of introducing a group into a compound having hydroxy group(s), which group is useful as a stable hydroxy-protecting group even in solid phase synthesis for the purpose of the extension of sugar chain under continuous acidic conditions and of being removed under mild conditions; sugar compounds protected by using said derivatives; and methods of protecting hydroxy group(s) using said derivatives.
    • 式(I)的叠氮基苄基衍生物,其中A是卤素原子,B是卤素原子或氢原子,X是与羟基反应的基团,使用所述衍生物保护羟基的方法和糖 至少一个羟基的氢原子被叠氮基卤代苄基取代的化合物。 根据本发明,提供了能够将基团引入到具有羟基的化合物中的新的衍生物,该基团即使在用于延长糖的目的的固相合成中也可用作稳定的羟基保护基 在连续酸性条件下并在温和条件下除去; 通过使用所述衍生物保护的糖化合物; 以及使用所述衍生物保护羟基的方法。
