  顺序促进一锅糖基化：寡糖合成抗肿瘤PI-88五糖的直接组装的前所未有的策略。

  摘要：

  目前正处于II期临床试验的抗肿瘤药物PI-88最具活性成分的五糖序列已迅速以高总收率组装，并且仅需三个步骤即可从三个单糖结构单元开始。该程序利用了第一个报道的仅在催化活化下进行的单锅连续糖苷化策略。另外，该程序仅依赖于贮存稳定且温和的启动子，例如Yb（OTf）3和Bi（OTf）3。

  Synthesis of 8-azidooctyl glycoside derivatives of the O-chain repeating unit of Escherichia coli O9a lipopolysaccharide and a methylated analog

  摘要：

  Described is the synthesis of 8-azidooctyl glycoside derivatives of the Escherichia coli serotype O9a O-chain tetrasaccharide repeating unit and the terminal tetrasaccharide motif in this polysaccharide, which contains a methyl group on O-3 of the distal mannopyranose residue. The assembly of these compounds involved the sequential addition of monosaccharide residues from the reducing to the nonreducing end of the molecule using glycosyl trichloroacetimidate donors. Both compounds were initially prepared as p-methoxyphenyl glycosides, which were converted to the corresponding 8-azidooctyl derivatives at a late stage in the synthesis. (C) 2008 Elsevier Ltd.

  A variety of benzylated 1-OH derivatives, having an acetyl or an allyl group, of D-glucose, D-galactose, D-mannose, D-xylose, L-arabinose, L-fucose, and L-rhamnose, were synthesized from the corresponding protected 2-methoxyethyl glycosides through a brief treatment with TiCl4 in dichloromethane and a subsequent hydrolysis of the intermediary 1-Cl derivatives on a silica-gel column.

  Cotrolled benzylation of methyl α-D-mannopyranoside with benzyl chloride and LiOH selectively gave the 2,3,6-tribenzyl ether in a 53% yield. Such a reaction using benzyl chloride and KOH afforded mainly the 2,4,6-tribenzyl ether in a 41% yield. The products were allylated and then hydrolyzed to give the corresponding 1-OH derivatives.
