Through a short series of reactions (catalytic oxidation, electrolytic decarboxylation, cyclization with alkaline nitromethane, and reduction), a conversion of N-acetyl-D-glucosamine (1) into hexaacetyl-streptamine (6) has been accomplished without previous protection of the hydroxyl groups in the starting compound (1), although the overall yield was not fully satisfactory. The conversion may represent a new and widely applicable means for the synthesis of diaminocyclitols from amino-sugars. A β-methoxyethoxymethyl ether function was unaffected during the anodic oxidation.
通过一系列短暂的反应(催化氧化、电解脱羧、与碱性硝基甲烷环化以及还原),成功将N-乙酰-D-氨基葡萄糖(1)转化为六乙酰-链霉胺(6),尽管整体产率并不十分令人满意,且在起始化合物(1)中未对羟基进行事先保护。这一转化可能代表了一种新的、广泛适用的从氨基糖合成二氨基环醇的方法。在阳极氧化过程中,β-甲氧乙氧基甲基醚功能未受影响。
