An approach to the synthesis of polyhydroxyazepane derivatives from sugar-based epoxyamides or epoxyalcohols, in which the total regioselective epoxide opening by nitrogen nucleophiles is the key step, is described. Thus, novel polyhydroxyazepane carboxamides and aminomethyl polyhydroxyazepanes, with potential pharmacological interest, are synthesized from diacetone d-mannose. Configurational assignments
描述了一种由糖基环氧酰胺或环氧醇合成多羟基氮杂环庚烷衍生物的方法,其中通过氮亲核试剂打开的总区域选择性环氧化物是关键步骤。因此,由双丙酮d-甘露糖合成了具有潜在药理学意义的新型聚羟基氮杂环庚烷羧酰胺和氨基甲基聚羟基氮杂环庚烷。确定了所获得产品的构型分配。
