The synthesis of (1→6), (1→4), and (1→1) linked aza-C-disaccharides, a novel class of glycomimetic compounds, is described. The polyhydroxylated piperidine ring was synthesized using vinyl bromide 11 as a common intermediate which was synthesized de novo from bromobenzene utilizing the microbial oxidation metabolite bromodiol 10. A Suzuki coupling of 11 with an alkylboron reagent derived from olefinated
描述了 (1→6)、(1→4) 和 (1→1) 连接的氮杂-C-二糖,一类新型糖模拟化合物的合成。多羟基哌啶环是使用溴化乙烯 11 作为常用中间体合成的,该中间体是利用微生物氧化代谢物溴二醇 10 从溴苯从头合成的。 11 与通过硼氢化反应从烯烃化碳水化合物前体衍生的烷基硼试剂的 Suzuki 偶联用于形成C-糖苷键。所得羰基官能团的臭氧分解和选择性还原用于产生氮杂糖环。在酸性脱保护后获得完全脱保护的氮杂-C-二糖。报道了针对几种常见糖苷酶的标题化合物的生物筛选以及体外抗 HIV 检测。
