Glycosyl Donors [Glyco Building Blocks] — includes activated sugar compounds such as trichloroacetimidates, thioglycosides, and glycosyl fluorides equipped with acetyl or pivaloyl protecting groups, designed to react as sugar unit donors in the formation of glycosidic bonds. The reactivity of the leaving group at the anomeric position is the hallmark of this compound group.
Glycosyl Donors are used by carbohydrate synthesis researchers to form glycosidic bonds with sugar acceptors through chemical activation using promoters such as Lewis acids or heavy metals, yielding oligosaccharides and complex glycoconjugates. Thioglycoside- and trichloroacetimidate-based donors are widely used in iterative glycosylation to build branched glycan structures that resemble natural glycans in glycobiology research.
