    摘要:
    N-乙酰神经氨酸丙酮酸裂解酶接受各种非氮源糖作为底物。丙酮酸与D-甘露糖的缩合产生3-脱氧-D-甘油-D-半乳糖-2-壬基磺酸(KDN),它是虹鳟鱼卵多唾液酸糖蛋白的一种成分。从一些容易得到的单糖制备其它ulosonic酸:3-脱氧-D-半乳-2-辛酮糖35dideoxy-D-葡糖-2- nonulosonic和37二脱氧D-半乳-2- nonulosonic酸。葡萄糖不是良好的底物,D-阿拉伯糖产生了预期的3-脱氧-D-葡萄糖的混合物-2-辛基磺酸(19%)和3-脱氧-D-甘露糖-2-辛基磺酸(16%)。后者是来自细菌多糖的众所周知的糖酸KDO,其是由缩合步骤中的异常取向导致的。通过保留2-脱氧-2- C -2-苯基-D-的76%收率的转化,证明了酶对糖的C(2)处的取代基的性质的相对冷漠,只要保留了D-甘露聚糖构型即可。甘露糖转化成35-二脱氧-5 - C-苯基-D-葡萄糖-2-壬基磺

  • Method of preparing 4-deoxy-D-mannose
    申请人:Japan Tobacco Inc.

    公开(公告)日:1994-02-09
    It is an object of the present invention is to provide a method of preparing 4-deoxy-D-mannose from widely available raw material selectively in a high yield. The method of the present invention comprises reducing a carbonyl group of the 2-position of levoglucosenone to convert to a hydroxyl group, adding an iodo-group to a double bond at the 4-position and an acyloxy group to the 3-position of levoglucosenone respectively, keeping a trans stereochemical relationship, forming a 1,6-anyhydro-4-deoxy-β-D-mannopyranose derivative having a deoxy from at the 4-position as the result of radical reduction of an iodo-group. The present invention make it possible to prepare a hard-obtaining rare sugar 4-deoxy-D-mannose in a high yield from starting levoglucosenone through a fewer processes than that of a convenient method including a reduction of a carbonyl group of levoglucosenone, an stereoselective addition reaction of an iodo-group and an acyloxy group to a double bond. Owning to this method, 4-deoxy-D-mannose used as not only a constitutional unit of useful sugar compounds including a sugar chain but also as a synthetic raw material can be readily supplied.
    本发明的目的是提供一种从可广泛获得的原料中选择性地高产制备 4-脱氧-D-甘露 糖的方法。本发明的方法包括将左旋葡烯酮 2 位的羰基还原转化为羟基,在左旋葡烯酮 4 位的双键上加入碘基,在 3 位上加入酰氧基,保持反式立体化学关系,形成 1,6-任意氢-4-脱氧-β-D-甘露糖衍生物,该衍生物具有 4 位上的脱氧,是碘基自由基还原的结果。本发明使从起始左旋葡烯酮制备难得的稀有糖类 4-脱氧-D-甘露糖成为可能,与包括左旋葡烯酮的羰基还原、碘基和酰氧基与双键的立体选择性加成反应的简便方法相比,本发明的制备过程更少。采用这种方法,不仅可以将 4-脱氧-D-甘露糖用作有用的糖化合物(包括糖链)的组成单位,还可以将其用作合成原料。
  • Catalyst regeneration
    申请人:CERESTAR HOLDING BV
    公开号:EP0710501A2
    公开(公告)日:1996-05-08
    The present invention relates to the regeneration of a supported molybdenum catalyst which has been used for the epimerisation of a saccharide. The preferred epimerisation is the conversion of glucose to mannose. The catalyst is regenerated by using an oxidising agent such as a peroxide. The regeneration step can be repeated several times. A further extension of the useful lifetime of the catalyst is obtained by including one or more washing steps.
    本发明涉及一种支撑钼催化剂的再生,该催化剂曾用于糖的表聚化。首选的二聚反应是将葡萄糖转化为甘露糖。使用过氧化物等氧化剂对催化剂进行再生。再生步骤可重复多次。通过加入一个或多个洗涤步骤,可进一步延长催化剂的使用寿命。
