  • Title: Synthesis of new amino sugar derivatives from keto-sugars of D-xylose.
    Author: Ji XM, Mo J, Liu HM, Sun HP.
    Journal: Carbohydr Res; 2006 Oct 16; 341(14):2312-20. PubMed ID: 16870167.
    Abstract:
    Several amino sugars and imino sugar derivatives were synthesized from keto-sugars of D-xylose through a series of reactions such as the Henry reaction, hydrogenation reactions, and nucleophilic addition reactions or substitution reactions. Thiazine derivative 15 was obtained by the reaction of the keto-sugar with NH(2)CSNH(2). Higher carbon sugar 16 was accidentally prepared at room temperature from the keto-sugar in the presence of NH(2)CONH(2). The structures of the compounds were confirmed by spectral analysis. The absolute configurations of all asymmetric carbon atoms of 6 and 8 were confirmed by X-ray crystallographic analysis.
