corresponding O -protected glycose phosphate diesters. O -Deisopropylidenation of the latter by aqueous trifluoroacetic acid afforded the target compound in 70% yield, based on the protected glycosides. Condensation of 1,2,3,4-tetra- O -acetyl-β- d -glucopyranose or -mannopyranose with double-tailed (perfluoroalkyl)alkyl hydrogenphosphonates or 10-eicosyl hydrogenphosphonate, via the coupling and oxidation
摘要:通过氢膦酸法合成了双尾d-葡萄糖3-和6-[[全氟烷基]烷基磷酸钠]。由双尾(全氟烷基)链烷醇和PCl 3-咪唑制得的稳定的双尾(全氟烷基)烷基氢膦酸酯,与1,2:3,4-二-O-异亚丙基-α-d-吡喃半乳糖反应,或与1,在Me 3 CCOCl作为缩合剂存在下的2:5,6-二-O-异亚丙基-α-d-葡萄糖基呋喃糖,在用碘水溶液氧化后,得到相应的O-保护的糖基磷酸二酯。基于被保护的糖苷,后者通过三氟乙酸水溶液的O-异异丙基亚胺化以70%的收率得到目标化合物。1,2,3的凝结 经由上述偶联和氧化步骤,具有双尾(全氟烷基)烷基氢膦酸酯或10-二十烷基氢膦酸酯的4-四-O-乙酰基-β-d-吡喃葡萄糖或-甘露吡喃糖提供了全-O-乙酰基葡萄糖磷酸二酯。基于保护的糖,用MeONa-MeOH的O-脱乙酰基以65%的收率实现。所有化合物均通过19 F,1 H,13 C和31 P NMR数据表征。初步的
