glycodendrimer synthesis, in which a 3,6-diallylated carbohydrate is utilised as core molecule, hydroboration-oxidation is the activating step, and glycosylation with branched and unbranched sugar trichloroacetimidates is used for dendritic growth. To obtain pure dendritic pseudo-tri- and -heptasaccharides in good yields, radical addition of mercaptoethanol to peripheral double bonds was also evaluated with
对于模拟作为细胞糖衣(称为糖萼)一部分的生物活性碳水化合物的高度分支特性,树状大分子化学是一个有吸引力的概念。因此,糖基糖精用于研究细胞表面发生的生物过程,例如细菌粘附。本文详细介绍了糖树状大分子合成的新方法,其中将3,6-二烯丙基化的碳水化合物用作核心分子,氢硼化-氧化是激活步骤,并使用支链和直链糖三氯乙酰亚氨酸的糖基化用于树突状生长。为了以高收率获得纯的树枝状伪三和庚糖,还评估了巯基乙醇向外围双键的自由基加成反应。
