efficient approach to 6-deoxy-heptose constructs has been established by one-carbon homologation of the sugar chain of hexoses. The reaction features the formation of sugar-based α-substituted propanedinitriles and ensuing diverse oxidative transformations under mild reaction conditions that are compatible with a wide range of sugars bearing various functional/protecting groups. The applications of this
已经通过己糖糖链的单碳同源建立了 6-脱氧-庚糖构建体的有效方法。该反应的特点是在温和的反应条件下形成糖基 α-取代的丙二腈并随后发生多种氧化转化,这些反应与带有各种功能/保护基团的各种糖相容。这种方法的应用通过空肠弯曲杆菌菌株 81-176 荚膜三糖重复单元衍生物的发散组装得到证明。
