  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.

  Synthesis of the C1-phosphonate analog of UDP-GlcNAc

  摘要：

  We describe the first synthesis of the Cl-phosphonate analog of UDP-GlcNAc, based on a new preparation of the corresponding glycosyl phosphonate. This C-glycosyl analog is shown to be a very weak inhibitor (K-i > 10 mM) of fungal chitin synthase, indicating that at least in this case the replacement of the anomeric oxygen with a methylene group is not an innocent substitution.

  treatment of the iodide with triethylphosphite to afford the corresponding phosphonate, deprotection of the hydroxy group, oxidation, oximation, catalytic hydrogenation and acetylation, afford the phosphono analogue of N-acetyl-α-D-mannosamine 1-phosphate.

  用二乙烯基锌对2,3,5-三-O-苄基-D-阿拉伯糖进行构图，随后进行巯基环化和碘脱汞立体选择性，得到α-C-吡喃葡萄糖基碘化物3，在C-2处具有游离羟基。暂时保护游离羟基，用亚磷酸三乙酯处理碘化物得到相应的膦酸酯，羟基去保护，氧化，肟化，催化氢化和乙酰化，得到N-乙酰基-α - D-甘露糖胺的膦酰基类似物1 -磷酸盐。
