Synthesis of a polymerizable, bivalent glycan mimetic of the HIV envelope spike gp120.


ABSTRACT: A synthetic study on the creation of a bivalent, ROMP capable monomer has the ability to be polymerized into the corresponding neo-glycopolymer mimetic of the surface glycans on gp120 envelope spike of the HIV virus. In our approach, we have developed a new strategy for orthogonally attaching both the terminal Man?1-2Man disaccharide unit of the D1 arm of Man9GlcNAc2 of HIV gp120 and the terminal Man?1-2 unit of its D2 arm to a bivalent scaffold to produce the corresponding polymerizable monomer. The Man?1-2 saccharide moieties were assembled using a nickel catalyst, Ni(4-F-PhCN)4(OTf)2, to activate trihaloacetimidate donors under mild and operationally simple procedure.
