  allyl 2-O-benzoyl-3,4-O-isopropylidene-α-L-fucopyranoside 在 吗啉 、 吡啶 、 四(三苯基膦)钯 、 三氟甲磺酸三甲基硅酯 、 4 A molecular sieve 、 对甲苯磺酸 、 溶剂黄146 、 三氟乙酸 作用下， 以 四氢呋喃 、 乙醇 、 二氯甲烷 、 水 、 甲苯 为溶剂， 反应 5.42h， 生成 allyl (4,6-di-O-acetyl-2-deoxy-2-phthalimido-β-D-glucopyranosyl)-(1->3)-2,4-di-O-benzoyl-α-L-fucopyranoside

  Synthesis and conjugation of a sulfated disaccharide involved in the aggregation process of the marine sponge Microciona prolifera

  摘要：

  The synthesis is reported of allyl (sodium 2-acetamido-2-deoxy-beta-D-glucopyranosyl 3-sulfate)-(1-->3)-alpha-L-fucopyranoside which represents an oligosaccharide fragment of the aggregation factor of the marine sponge Microciona prolifera. The title compound was obtained by coupling of 3-O-allyloxycarbonyl-2-deoxy-4,6-O-isopropylidene-2-phthalimido-beta-D-glucopyranosyl trichloroacetimidate with allyl 2,4-di-O-benzoyl-alpha-Lfucopyranoside, followed by de-isopropylidenation, acetylation, de-allyloxycarbonylation, sulfation, de-acylation, and finally N-acetylation. The allyl glycoside was eventually converted into a 3-(2-aminoethylthio)propyl glycoside and then coupled to bovine serum albumin (BSA) using diethyl squarate as the bivalent linker, yielding 8 hapten molecules per molecule of BSA.
