Generally applicable and stereoselective formation of 1,2-cis-glycopyranosidic linkage remains a long sought after yet unmet goal in carbohydrate chemistry. This work advances a strategy to this challenge via stereoinversion at the anomeric position of 1,2-trans glycosyl ester donors. This SN2 glycosylation is enabled under gold catalysis by an oxazole-based directing group optimally tethered to a leaving group and achieved under mild catalytic conditions, in mostly excellent yields, and with good to outstanding selectivities. The strategy is also applied to the synthesis of oligosaccharides.

Anti-heparanase compounds for the treatment of cancer are described. The anti-heparanase compounds are high affinity, synthetic glycopolymers that result in minimal anticoagulant activity. Stereoselective fluorinated forms of these compounds are also prov

A flexible 1,2-cis α-selective glycosylation strategy for a wide range of glycosyl donors and acceptors has been developed, which is based on an in situ adduct transformation protocol. Based on this strategy, both NFM-derived and iodide covalent adducts c
