  A series of new 2-, 3- and 4-benzylamino-2-, 3- and 4-deoxy derivatives of 1,6-anhydro-β-D-hexopyranoses were prepared from 1,6:2,3- and 1,6:3,4-dianhydro-β-D-hexopyranoses by treatment with benzylamine and converted into 2,3-(N-benzylepimino)-2,3-dideoxy- and 3,4-(N-benzylepimino)-3,4-dideoxy-β-D-hexopyranoses of the D-allo, D-galacto and D-talo configuration by Mitsunobu reaction. The structures of benzylamino and benzylimino derivatives were confirmed by ¹H and ¹³C NMR spectra.

  When the series of 2-, 3-, and 4-(benzylamino)-2-, 3-, and 4-deoxy derivatives of 1,6-anhydro-beta-D-hexopyranoses in the D-gluco, D-lyxo, and D-arabino configurations were reacted with diisopropyl azodicarboxylate, N-benzyl groups were selectively cleaved in the presence of O-benzyl groups. The yields ranged from 51 to 97%. The debenzylation of some aliphatic benzylamines is also discussed.

  The selective deprotection of N-benzyl group was achieved in the presence of azido, O-benzyl, and N-tosyl groups in reactions of benzylamines derived from 1,6-anhydro-β-d-glucopyranose with diisopropyl azodicarboxylate (DIAD) in THF. The key role of this solvent and the reaction pathway are presented together with proven reaction intermediates.

• Preparation of diamino pseudodisaccharide derivatives from 1,6-anhydro-β-d-hexopyranoses via aziridine-ring cleavage
  作者：Jiří Kroutil、Miloš Buděšínský

  DOI：10.1016/j.carres.2006.11.028

  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.
