  利用有效衍生自D-甘露糖的甲基4-叠氮基-4,6-二脱氧-α-D-甘露吡喃糖苷合成布鲁氏菌A抗原的抗原决定簇。

  摘要：

  描述了一种合成含有2-连接的4,6-二脱氧-4-甲酰胺基-α-D-甘露吡喃糖基残基的布鲁氏菌O抗原决定簇的策略。所采用的方法还允许改变N-酰基部分。由D-甘露糖以10-20g的规模高产率合成甲基4-叠氮基-4,6-二脱氧-α-D-甘露吡喃糖苷提供了关键的中间体。7的区域选择性乙酰化得到2-乙酸酯8，其用三氯乙酰亚胺苄基酯处理后，提供了甲基2-O-乙酰基-4-叠氮基-3-O-苄基-4，6-二脱氧-α-D-甘露吡喃糖苷。该化合物用作糖基供体12和受体10分子的共同前体。三氟甲磺酸银促进的10乘12的糖基化反应产生了二糖衍生物，其经氢解后生成了甲基4-氨基-2-O-（4-氨基-4,6-二脱氧-α-D-甘露吡喃糖基）-4，从中获得N-甲酰基和N-乙酰基衍生物的6-二脱氧-α-D-甘露吡喃糖苷。13脱乙酰基，然后与12进行糖基化，得到三糖衍生物。N-甲酰化的二糖17抑制布鲁氏菌O-多糖与布鲁氏菌特异性单克隆抗体的结合。

• Synthesis of methyl α-glycosides of some higher oligosaccharide fragments of the O-antigen of Vibrio cholerae O1, serotype Inaba and Ogawa
  作者：Jian Zhang、Pavol Kováč

  DOI：10.1016/s0008-6215(97)00070-0

  日期：1997.5

  The title oligosaccharides, the tri- through the hexasaccharide in the Inaba series and the penta- and the hexasaccharide in the Ogawa series, have been synthesized using 1-thioglycosides of precursors to 3-O-benzyl-perosamine (4-amino-4,6-dideoxy-D-mannose) as building blocks and N-iodosuccinimide/silver triflate as a promoter. The azido groups in the assembled oligosaccharides were reduced to amino groups, which were then acylated using 2,4-O-benzylidene-3-deoxy-L-glycero-tetronic acid as the derivatizing reagent. Catalytic hydrogenolysis, simultaneously of the benzyl and benzylidene groups, gave the desired products that were characterized by H-1 and C-13 NMR spectroscopy. (C) 1997 Elsevier Science Ltd.
