Galactofuranose sugar units are essential for the production of the cell coat of many pathogenic microorganisms. This sugar is not found in mammals, and so compounds that may interfere with the biosynthetic processing of this sugar unit provide interesting targets for drug design. This paper describes the use of a cyanation reaction for the production of a one-carbon extension of a galactofuranosylic
半乳糖呋喃糖糖单元对于生产许多病原微生物的细胞被膜至关重要。在哺乳动物中找不到这种糖,因此可能干扰该糖单元生物合成过程的化合物为药物设计提供了有趣的目标。本文描述了氰化反应用于在C-1生成半乳糖呋喃糖基单元的一个碳原子延伸的反应,得到2,5-脱水-3,4,6,7-四-O-苯甲酰基-D-甘油-L-甘露聚糖-庚腈。报道了有效水解引入的腈基以产生甲酯的方法,以及相应的α,β-不饱和和3-脱氧酯衍生物的合成方法。
