  Synthesis of 1,4-anhydro-d-fructose and 1,4-anhydro-d-tagatose

  摘要：

  1,4-Anhydro-D-fructose and 1,4-anhydro-D-tagatose were prepared from 1,2-O-isopropylidene-D-glucofuranose via the common intermediate 3,5,6-tri-O-benzyl-D-glucitol. The title compounds may be interesting anti-oxidants and feature activities akin to their natural pyranoid counterpart, 1,5-anhydro-D-fructose. (c) 2006 Elsevier Ltd. All rights reserved.

  The present invention relates to 1,4- and 1,5-anhydro-D-ketoses (monosaccharides, oligosaccharides and various glycoconjugates), e.g. 1,5-anhydro-D-fructose. Moreover, the invention provides synthetic methods and novel intermediates and precursors suitable for their preparation. The methods include catalytic- and/or pyrolitic sulfenic acid elimination of corresponding ß-hydroxy sulfoxides, N-deprotection of N-substituted-aminoglycals, O-deprotection of carbohydrate enolethers and/or O-acyl-substituted carbohydrate enols, and regio- and stereoselective modification and subsequent chemical transformation of bicyclic and/or tricyclic 1,4- and 1,5-anhydro-glycoderivatives. Furthermore, the present invention provides novel applications of 1,4- and 1,5-anhydroketoses within pharmaceutical, food and cosmetic industries.
