Abstract

A new, efficient and easy synthesis of multivalent mannoside neoglyconjugates is described by the alkynylation reaction of lithium acetylides derived from adequately protected propargyl α-d-mannoside and readily available polyalkylcarboxylate benzene derivatives as scaffolds.

2-Propynyl α-d-mannopyranoside was synthesized from per-O-acetyl α-d-mannopyranoside and propargyl alcohol following the procedure described by Mereyala et al. [20]
