  二苄基和二苯基磷酸铯在立体选择性合成磷酸糖基衍生物中的用途

  摘要：

  β-糖基二苄基磷酸酯的过乙酸盐在二苄基磷酸铯与衍生自 1-吡喃岩藻糖、d-吡喃半乳糖和 2-叠氮基-2-脱氧-d-吡喃半乳糖或三-O的过乙酰-α-糖基硝酸盐反应中有效形成-乙酰-α-1-吡喃岩藻糖基溴。相反，上述糖基硝酸盐与二苯基磷酸铯的反应通过相应β-端基异构体的中间体形成导致热力学上更稳定的α-糖基二苯基磷酸酯。

  Acetylated α-glycosyl nitrates were efficiently converted under mild conditions into protected β-glycosyl phosphates by treatment with cesium dibenzyl phosphate or into thermodynamically more stable α-glycosyl phosphate derivatives upon interaction with cesium diphenyl phosphate. These reactions were found to be applicable both to 2-azido-2,6-dideoxy- and 2-azido-2-deoxygalactopyranosyl nitrates as

  通过用磷酸二苄基铯处理，乙酰化的α-糖基硝酸酯在温和的条件下可以有效地转化为受保护的β-糖基磷酸酯，或者在与磷酸二苯酯铯相互作用时转化为热力学上更稳定的α-糖基磷酸酯衍生物。发现这些反应适用于2-叠氮基2，6-二脱氧-和2-叠氮基2-脱氧半乳糖吡喃糖基硝酸盐以及6-脱氧半乳糖吡喃糖基和半乳糖吡喃糖基的衍生物。

  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.
