Click Multivalent Heterogeneous Neoglycoconjugates - Modular Synthesis and Evaluation of Their Binding Affinities
The efficient synthesis of structurally diverse, multivalent, heterogeneous neoglycoconjugates by means of a series of different click-based strategies is described. The methodology is highly efficient and versatile allowing for easy access to a series of mannose (α-Man)-containing glycoconjugates differing in their valency, nature of the scaffold, nature of the constitutive sugars and length of the

Synthesis of a Nonavalent Mannoside Glycodendrimer Based on Pentaerythritol

A nonavalent glycodendrimer bearing terminal alpha-D-mannopyranoside units has been synthesized with a convergent approach. Terminal trivalent mannoside dendrons bearing p-halophenyl ethers were prepared by glycosylation of pentaerythritol derivatives having three 2-hydroxyethyl ether substituents. Two efficient routes were developed for the synthesis of the pentaerythritol-based core (17), which has three terminal propargyl ethers. Conditions were found under which the triple Sonogashira coupling reaction of the dendron and the tri-O-propargyl ether (17) proceeded efficiently. The product was deprotected and it and precursors were fully characterized by NMR spectroscopy and FT-ICR mass spectrometry.
