  Synthesis of Epoxyalkyl (1→3)‐β‐D‐Oligoglucosides

  摘要：

  We describe an approach for the synthesis of (1 --> 3)-beta-D-oligosaccharide derivatives 10-18. 1-9 were synthesized by treating peracetylated (1 --> 3)-beta-D-oligosaccharides with the corresponding alkenyl alcohols and Lewis acid (SnCl4) catalyst. Epoxidation of the corresponding alkenyl oligoglucosides took place by m-CPBA. NaOMe in dry methanol was used for the deacetylation of the blocked derivatives, to give 10-18 in overall yields of 25-32%.
