  Gold catalyzed glycosidations for the synthesis of sugar acrylate/acrylamide hybrids and their utility

  摘要：

  Propargyl glyco 1,2-orthoesters were exploited for the efficient synthesis of interesting glycomonomers such as glyco-acrylates and acrylamides using gold catalysts. It was observed that propargyl glyco 1,2-orthoesters with hydroxyethyl acrylates gives very good yield of the corresponding glyco-acrylates in a single step in the presence of catalytic amount of gold(III) catalyst; whereas, gold catalyzed glycosidation reaction on hydroxyethyl acrylamides was found to yield the corresponding acrylamidoyl 1,2-orthoester which was then converted to the corresponding glycol-acrylamide in the presence of catalytic amount of TMSOTf. Synthesized glyco-acrylate/acrylamide monomers are shown to undergo thiolate addition as well as free radical polymerization (C) 2011 Elsevier Ltd. All rights reserved.

  摘要：

  复杂的寡糖合成需要使用一个以上的糖基供体，因此，糖基供体之间的相互转化方法对整个合成计划非常重要。在这里，正戊烯基糖苷在酸和碱敏感官能团的存在下被有效地转化为糖基 1,2-O-正酯。发现所确定的方案也适用于合成三糖基和四糖基 1,2-O-缩酮。此外，该方法还完成了结核分枝杆菌细胞表面五碳呋喃糖苷的迭代合成。

  Selective activation of propargyl 1,2-orthoesters in the presence of propargyl glycosides and propargyl ethers was studied; a catalytic amount of AuBr3 activated the propargyloxy group of the 1,2-orthoester thereby giving access to disaccharides with the propargyl group at the reducing end; furthermore, propargyl ethers were unaffected under the reaction conditions.
