  Synthesis of Glycosyl Glycerols and Related Glycolipids

  摘要：

  Several isomeric glycosyl glycerols were synthesized. Acetylated allyl glycosides of D-glucose and D-galactose were transformed into 1-O-(glycopyranosyl)-rac-glycerols in a three step procedure via the corresponding 2,3-epoxypropyl glycosides and the peracetylated glycosyl glycerols. Tetra-O-benzyl-D-glucose was glycosylated with 1,3-di-O-benzylglycerol to give the alpha-anomer preferentially. The 2-O-(tetra-O-acetyl-beta-glycopyranosyl)-sn-glycerols and 2-O-(beta-glycopyranosyl)-sn-glycerols of D-glucose, D-galactose and N-acetyl-D-glucosamine and the corresponding alpha-derivatives of D-mannose were synthesized by selective glycosylation methods from 1,3-di-O-benzylglycerol and 1,3-O-benzylideneglycerol, respectively, and activated sugar compounds followed by hydrogenolysis. After long chain acylation and selective deacetylation the 1,3-di-O-acyl-2-O-(beta-glycopyranosyl)-sn-glycerols of D-glucose, D-galactose and N-acetyl-D-glucosamine and the corresponding a-derivative of D-mannose were synthesized.

  (1→4)-linked disaccharides. About 35–40% of (1→6)-and 15–20% of (1→4)-linked disaccharides were oxidatively degraded to smaller molecules after incubation for 24 h. Of the four disaccharides examined, namely, maltose, isomaltose, cellobiose, and gentiobiose, the α-(1→6)-linked disaccharide isomaltose exhibited the highest reactivity, whereas the β-(1→4)-linked disaccharide cellobiose showed the lowest

  摘要研究了在生理条件下，以麦芽糖和异麦芽糖为主的（1→4）-和（1→6）连接的二糖与Fenton试剂的反应。通过glc和glc-ms的三甲基甲硅烷基衍生物对氧化产物进行化学表征，结果表明（1→6）连接的二糖与芬顿试剂产生的羟基自由基（·OH）的反应性大于（1）。 →4）-连接的二糖。孵育24小时后，约35-40％（1→6）-和15-20％（1→4）连接的二糖被氧化降解成较小的分子。在所检查的四种二糖中，即麦芽糖，异麦芽糖，纤维二糖和龙胆二糖，α-（1→6）连接的二糖异麦芽糖表现出最高的反应性，而β-（1→4）连接的二糖纤维二糖表现出最低的反应性。 。
