  摘要：

  The aziridine ring cleavage of N-nosylepimines 3 and 7 having D-allo and D-manno configurations with halides led regioselectively to N-o-nitrobenzenesulfonylated 2-halo-3-amino- and 3-halo-2-amino-2,3-dideoxy derivatives of 1,6-anhydro-beta-D-glucopyranose 8-14 in 59-81% yields. Removal of o-nitrobenzenesulfonyl protecting group with benzenethiol afforded aminosaccharides, which were converted into more stable hydrochlorides 15-18. (C) 2003 Elsevier Ltd.

  日期：——

  Aziridine ring cleavage reactions of five N-nosylepimines (2-6) having D-talo, D-galacto, D-manno, and D-allo configurations with potassium hydrogendifluoride under various reaction conditions have been performed. The cleavage regioselectively afforded diaxial isomers of vicinal amino-fluoro derivatives of 1,6-anhydro-β-D-gluco- and mannopyranose 7-11 in 51-94% yields. Removal of 2-nitrobenzenesulfonyl protecting group with benzenethiol has been attempted in the case of compound 10.

  对五种具有D-talo、D-galacto、D-manno和D-allo构型的N-烷基环丙胺（2-6）进行了钾氢二氟化物催化的环丙胺环开裂反应，在不同的反应条件下进行了实验。该开裂反应选择性地生成了1,6-脱水-β-D-葡萄和甘露糖衍生物的二轴异构体氨基-氟衍生物（7-11），产率为51-94%。在化合物10的情况下尝试了用苯硫醇去除2-硝基苯磺酰保护基。
• Preparation of diamino pseudodisaccharide derivatives from 1,6-anhydro-β-d-hexopyranoses via aziridine-ring cleavage
  作者：Jiří Kroutil、Miloš Buděšínský

  日期：2007.2

  Twelve positional isomers of diamino pseudodisaccharide derivatives with gluco-gluco configuration have been prepared using aziridine-ring cleavage of epimino derivatives of 1,6-anhydro-beta-D-hexopyranoses of the D-allo, D-manno, and D-galacto configuration by 2-, 3-, and 4-amino derivatives of 1,6-anhydro-beta-D-glucopyranose. The N-substitution of the aziridine ring by a 2-nitrobenzenesulfonyl group and ionic-liquid solvent (N-methylpyridinium tosylate) was used to obtain cleavage products in high yield (64-93%). The cleavage reactions proceeded according to the Furst-Plattner rule and only trans-diaxial stereoisomers were formed. (c) 2006 Elsevier Ltd. All rights reserved.
