A 2′,6′-diamino-1,6-anhydro disaccharide derivative (6) was prepared from maltose. The 3′,4′-diol system of 6 was successfully converted into the 3′-ene system by application of the Corey–Winter procedure, giving the hex-3′-enopyranose derivative (8). Catalytic hydrogenation of 8 gave the dideoxy derivative, a key intermediate for the synthesis of a new aminoglycoside.
由麦芽糖制备 2',6'-二氨基-1,6-脱水二糖衍生物 (6)。通过应用 Corey-Winter 程序,6 的 3',4'-二醇体系成功转化为 3'-烯体系,得到 hex-3'-enopyranose 衍生物 (8)。8 的催化氢化得到双脱氧衍生物,这是合成新氨基糖苷的关键中间体。
