  Synthesis of α- and β-C-glycosides of N-acetylglucosamine

  摘要：

  As part of efforts to make available new, classes of bioactive C-glycoconjugates, D-glucosamine has been effectively converted into a series of 2-deoxy-2-amino-C-glycosides. This versatile approach is keyed by a remarkably effective metal catalyzed olefin isomerization of the isomeric C-allyl amino sugars which, in turn, are readily available via radical allylation of D-glucosamine.

  derivatives (6a or 6b) afforded, respectively, the ester 12 and amide 14. The dihydroxylation of the conjugated double bond in ester 12 or amide 14 was better achieved with osmium tetraoxide/barium chlorate, leading to the expected diols 13 and 15 as a mixture of two diastereoisomers. The desired compounds 1-4 were obtained after catalytic hydrogenation of compounds 12-15.

  日期：2005.2

  Boron trichloride has been found to promote selective deprotection of 1,2- or 1,3-cis oriented secondary benzyl ethers of per-benzylated C-glycosyl derivatives. The reactivity towards BCl(3) follows the order: C-4>or=C-2>C-6>C-3 for C-glucopyranosyl derivatives and C-3>or=C-4>C-6>C-2 for C-galactopyranosyl derivatives. Preparatively useful selective debenzylation at secondary positions was possible

• INVESTIGATION OF THE SHARPLESS ASYMMETRIC AMINOHYDROXYLATION WITH <i>C</i>-ALLYL GLYCOSIDES
  作者：Juan Xie、Jean-Marc Valéry

  日期：2001.7.31

  We have studied the Sharpless asymmetric aminohydroxylation on C-allyl glycosides in order to prepare C-glycosyl aminoacids or C-glycopeptides. The perbenzylated amino α-C-allyl glucoside 1 and β-C-allyl glucoside 2 were shown to be moderate substrates for this reaction. New C-glycosyl α-amino ketones were isolated after oxidation of the crude β-amino alcohols.
