The usefulness of N,N′-diacetylchitobiose (1) as a starting material for syntheses of biologically active compounds was shown by converting allyl chitobioside 5 into O-(2-acetamido-2-deoxy-β-D-glucopyranosyl)-(1→4)-2-acetamido-1,2,5-trideoxy-1,5-imino-D-glucitol (2), which would be a potential glycosidase inhibitor. The conversion includes a discriminative modification of two amino groups existing
通过将烯丙基壳糖苷5转化为O-(2-乙酰氨基-2-脱氧-β-D-吡喃葡萄糖基)-(1 ),可以证明N,N'-二乙酰基壳二糖(1)作为合成生物活性化合物的原料的有用性。→4)-2-乙酰氨基-1,2,5-三苯氧基-1,5-亚氨基-D-葡萄糖醇(2),这可能是一种潜在的糖苷酶抑制剂。该转化包括对存在于二糖中间体8中的两个氨基的区别修饰,叠氮基的区域选择性引入和利用分子内氨基环化的哌啶环的构建。
