In connection with studies on lipopolysaccharide biosynthesis in respiratory pathogens we had a need to access potential biosynthetic intermediate sugar nucleotides. Herein we report the chemical synthesis of uridine 5′-diphospho 2,3-diacetamido-2,3-dideoxy-α-D-glucuronic acid (UDP-Glc-2,3-diNAcA) (1) from N-acetyl-D-glucosamine in 17 steps and ∼9% overall yield. This compound has proved invaluable
关于呼吸道病原体中脂多糖生物合成的研究,我们需要获得潜在的生物合成中间糖核苷酸。在此我们报告了化学合成尿苷5'-二磷酸 2,3-diacetamido-2,3-dideoxy-α- D - glucuronic acid (UDP-Glc-2,3-diNAcA) ( 1 ) 从N-乙酰基-D-氨基葡萄糖分 17 个步骤,总产率约为 9%。该化合物在阐明导致形成含 2,3-二乙酰氨基-2,3-双脱氧-D-甘露糖醛酸的多糖的生物合成途径方面已被证明是无价的。
