  描述：

  2-amino-3,4-di-O-acetyl-2-deoxy-α-D-fucopyranosyl phosphate 在 三正丁胺 作用下， 以 四氢呋喃 、 1,4-二氧六环 、 水 为溶剂， 反应 35.25h， 生成 disodium uridine 5'-(2-acetamido-2-deoxy-α-D-fucopyranosyl diphosphate)

  摘要：

  In connection with studies on the biosynthesis of capsular polysaccharides from Staphylococcus aureus, a new synthesis of uridine 5'-(2-acetamido-2,6-dideoxy-alpha-D-galactopyranosyl diphosphate) (uridine 5'-diphospho-N-acetyl-alpha-D-fucosamine) using 2-azido-3,4-di-O-acetyl-2,6-dideoxy-alpha-D-galactopyranosyl nitrate as the key intermediate was carried out. The reaction of this product with cesium dibenzyl phosphate smoothly affords the corresponding beta-glycosyl dibenzyl phosphate, which undergoes anomerization on treatment with BF(3).Et(2)O and 2-bromopyridine to give alpha-glycosyl dibenzyl phosphate in high yield. This product was then transformed into 2-amino-3,4-di-O-acetyl-2,6-dideoxy-alpha-D-galactopyranosyl phosphate, subsequently converted into 2-acetamido-2,6-dideoxy-alpha-D-galactopyranosyl phosphate and the target nucleoside diphosphate sugar.
