  Stereoselective Synthesis of the Isosteric Phosphono Analogues of N-Acetyl-α-d-glucosamine 1-Phosphate and N-Acetyl-α-d-mannosamine 1-Phosphate

  摘要：

  The isosteric phosphono analogues of N-acetyl-alpha-D-glucosamine I-phosphate and N-acetyl-alpha-D-mannosamine l-phosphate (1 and 2) are stereoselectively synthesized starting from 2,3,5-tri-O-benzyl-D-arabinose (3b). Reaction of 3b with divinylzinc stereoselectively affords the glucoenitol 4c, the mercuriocyclization and subsequent iododemercuriation of which stereoselectively afford the alpha-C-glucopyranosyl iodide 6b with a free hydroxyl group at C-2. Temporary protection of the hydroxyl group and treatment with triethyl phosphite converts 6b into the corresponding phosphonate 7b. The free hydroxyl group of 7b is then converted into an acetamido group by oximation, acetylation of the oxime, reduction, and subsequent acetylation. The reduction of the oxime with diborane stereoselectively affords the gluco isomer, whereas catalytic hydrogenation gives the manno isomer. Acetylation and deprotection afford the desired products 1 and 2.

  Examples of synthetic C-phosphonate analogues of microbial polysaccharide structures containing inter-residue phosphodiester linkages are most rare. The successful construction of such analogues of the Neisseria meningitidis Group A capsular polysaccharide is described. Using a modified Mitsunobu reaction (tris(4-chlorophenyl)phosphine, DIAD, excess of Et3N) between an anomeric C-phosphonate monoester

  含有残基间磷酸二酯键的微生物多糖结构的合成C-膦酸酯类似物的例子是最罕见的。描述了脑膜炎奈瑟氏球菌A类荚膜多糖的此类类似物的成功构建。使用异头C-膦酸酯单酯和6-OH ManNAc受体之间的修饰的Mitsunobu反应（三（4-氯苯基）膦，DIAD，过量的Et3N），可获得高产率（88％）的二聚体。通过脱乙酰基将二聚体转化为新的6-OH受体，并在相同条件下与延伸的C-膦酸酯单体进一步反应，以92％的收率得到三聚体。然后重复该过程，得到四聚体，其偶联产率为85％。那个
