报告简介:
Glycosylation methods initiated by non-ionic processes have significant, but underexplored potential. In order to better exploit the power the such glycosylation methods, we have developed a range of bench stable glycosyl donors that can be readily prepared from simple starting materials. These donors can be activated to form glycosyl radicals or glycosyl transition metal complexes under mild conditions. Enabled by the use of these donors, we have developed a series of glycosylation methods and accomplished synthesis of diverse glycoconjugates that were previously difficult to access. In many cases, no protecting group on glycosyl donors is required. Moreover, it allows the utilization of external, delicate reagents or catalysts to control stereoselectivity, which is another essential task in carbohydrate synthesis.
