amino sugars and imino sugar derivatives were synthesized from keto-sugars of D-xylose through a series of reactions such as the Henry reaction, hydrogenation reactions, and nucleophilic addition reactions or substitution reactions. Thiazine derivative 15 was obtained by the reaction of the keto-sugar with NH(2)CSNH(2). Higher carbon sugar 16 was accidentally prepared at room temperature from the keto-sugar
通过一系列反应,例如亨利反应,氢化反应,亲核加成反应或取代反应,从D-木糖的酮糖合成了几种氨基糖和亚氨基糖衍生物。通过使酮糖与NH(2)CSNH(2)反应获得噻嗪衍生物15。在室温下,在NH(2)CONH(2)存在的情况下,从酮糖意外地制备了高级碳糖16。化合物的结构通过光谱分析确认。通过X射线晶体学分析证实了6和8的所有不对称碳原子的绝对构型。
