  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.

• Analogues of the mycobacterial arabinogalactan linkage disaccharide as cell wall biosynthesis inhibitors

  The mycobacterial arabinogalactan linkage disaccharide [alpha-(L)-Rha-(1 --> 3)-alpha-D-GlcNAc] provides a basis for the design of new antitubercular drugs, since it supports a key skeletal structure in the bacterial cell wall. A series of analogues of the linker was synthesized by coupling appropriate thiorhamnosyl donors modified at their 4-positions, with an N-acetyl glucosamine acceptor. In a cell-free enzyme inhibition assay, three analogues inhibited the activity of the galactosyltransferase that adds a Galf residue to the linkage disaccharide. Although the compounds were modest inhibitors, these data confirm the viability of this approach to anti-mycobacterial agents. It is especially significant that the three effective compounds are modified at the site of the acceptor atom in the natural substrate. (C) 2003 Elsevier Ltd. All rights reserved.
