    Stereoselective synthesis of nonsymmetrical difructose dianhydrides from xylylene-tethered d-fructose precursors
    摘要:
    Nonsymmetrical furanose-pyranose difructose dianhydrides (DFAs), a class of cyclic disaccharides present in foodstuffs, have been prepared in high yield by connecting the reacting monosaccharide moieties through a xylylene bridge prior to triflic acid-promoted bis-spiroketalization. The reaction can then proceed either intra- or intermolecularly, both the regio- and the stereoselectivity being strongly dependent on the spacer length. Noteworthy, the longer m- and p-xylylene positional isomers led to the thermodynamic alpha-D-fructofuranose beta-D-fructopyranose 1,2':2,1'-dyanhydride 1, the major DFA in commercial caramel, in a stereoselective manner. The shorter o-xylylene tether afforded preferentially the elusive contra-thermodynamic beta-D-fructofuranose alpha-D-fructopyranose diastereomer 2, a trace constituent of caramel. The results have been rationalized in terms of stereoelectronic and conformational properties and offer new perspectives for the preparation of pure DFA standards for analytical and nutritional studies.

  • Spacer-Mediated Synthesis of Bis-spiroketal Disaccharides: Nonsymmetrical Furanose-Pyranose Difructose Dianhydrides
    作者:Carmen Ortiz Mellet、José García Fernández、Farida Louis、M. García-Moreno、Patricia Balbuena

    The stereochemical outcome of the dimerization reaction of d-fructose, leading to tricyclic bis-spiroketal systems, can be tuned by inserting a xylylene template between the reacting ­moieties. Spirocyclization becomes then an intramolecular process, the available conformational space depending on the nature of the tether. The methodology is here illustrated by the stereoselective synthesis of two nonsymmetrical di-d-fructose dianhydrides present in commercial caramel.
