  描述：

  ethyl 2,3,4-tri-O-methyl-1-thio-α-D-glucopyranoside 在 吡啶 、 正丁基锂 作用下， 以 四氢呋喃 、 正己烷 、 二氯甲烷 为溶剂， 反应 1.0h， 生成 ethyl 6-deoxy-6-C-(ethyl sulfonatomethyl)-2,3,4-tri-O-methyl-1-thio-α-D-glucopyranoside

  名称：

  Large-scale synthesis of 6-deoxy-6-sulfonatomethyl glycosides and their application for novel synthesis of a heparinoid pentasaccharide trisulfonic acid of anticoagulant activity

  摘要：

  Multigram-scale syntheses of three 6-deoxy-6-sulfonatomethyl a-glucosides were accomplished via reactions of the corresponding primary triflate derivatives with the lithiated ethyl methanesulfonate. Chemoselective glycosylation reactions of different 6-C-sulfonatomethyl glucoside donors were studied. The sulfonic acid-containing building blocks were utilised in a novel [2+3] block synthesis of a trisulfonic acid isoster of the anticoagulant pentasaccharide idraparinux. (C) 2014 Elsevier Ltd.
