Abstract

Glycosyl/glycal metal functionalization has emerged as an efficient protocol for the construction of glycosides. Benefitting from the rapid development of organometallic chemistry and transition-metal-catalyzed cross-coupling reactions, glycosyl-metal-mediated glycosylation has significantly expanded the space for glycoside synthesis recently. In this short review, we underscore the representative progress in this area, categorizing the advancements by the type of glycosyl/glycal metal species. The reaction mechanism, stereochemical control, synthetic utility, and unmet challenges are also discussed.
