group participation actually enhance the reactivity of the anomeric center when the participating group is inherently disarming? To investigate the influence of the neighboring group effect from a 2-O protective group on acidic glycoside hydrolysis, 10 methyl glucosides having different protective groups on O2 have been synthesized and a clear trend between anomeric configuration, participation of the
当参与小组固有地撤防时,邻近小组的参与是否真的增强了异头中心的反应性?为了研究2-O保护基的邻近基团效应对酸性糖苷水解的影响,已合成了在O2上具有不同保护基的10个甲基葡糖苷,并且端基异构构型,保护基的参与和速率之间存在明显的趋势。可以观察到水解的增加。
