We have investigated the use of sonication for the synthesis of oligomannosides. A convenient sonication-mediated glycosylation protocol that is applicable to traditional glycosylation methods has been developed. This protocol can be applicable for activating glycosyl donors that are known to have low reactivity which enable the synthesis of oligomannosides of particular biological interest with the same efficiency.

for synthesizing reverse glycosylfluorides is described, relying on silver-promoted decarboxylative fluorination of structurally diverse pentofuran- and hexopyranuronic acids under the mild reaction conditions. The potential applications of the reaction are further demonstrated by converting readily available d-uronic acid derivatives into uncommon d-/l-glycosyl fluorides through a C1-to-C5 switch
