  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.

  Synthesis of alpha-C-ethylene phosphate and phosphonate as well as alpha-C-methylene phosphate analogues of N-acetyl-alpha-D-glucosamine I-phosphate is reported starting from the common perbenzylated 2-acetamido-2-deoxy-alpha-C-allyl glucoside. Anomerisation of the corresponding amino alpha-C-glucosyl aldehyde to the beta-aldehyde was observed. Thus, both amino alpha- and beta-C-glucosyl methanol were obtained after reduction.

  A highly effective method for the introduction of a formyl group at the anomeric position of pyranosides was developed via enolisation Of beta-C-D-glycopyranosylpropan-2-one using thermodynamic conditions then oxidative cleavage of the more substituted double bond. This sequence affords the desired aldehydes that are conveniently protected as aminals for purification and storage and easily regenerated using Dowex resin H+. In this paper, the syntheses of nine differently protected aldehydes derived from D-glucose, D-galactose. lactose and N-acetyl-D-glucosamine are presented. Our strategy proved to be very efficient in most cases excepted in the D-mannose series. (C) 2007 Elsevier Ltd. All rights reserved.
