A divergent synthesis of (-)-4-epi-shikimic acid was developed. This route features a one-pot zinc-mediated reductive ring opening of an arabinofuranose followed by a Barbier reaction and culminates in a ring-closing metathesis. Functionalization of (-)-4-epi-shikimic acid via conjugate addition of a thiol occurs in high diastereoselectivity to afford a(More)
Glycans are key participants in biological processes ranging from reproduction to cellular communication to infection. Revealing glycan roles and the underlying molecular mechanisms by which glycans manifest their function requires access to glycan derivatives that vary systematically. To this end, glycopolymers (polymers bearing pendant carbohydrates) have(More)
An understanding of the biological roles of lectins will be advanced by ligands that can inhibit or even recruit lectin function. To this end, glycomimetics, noncarbohydrate ligands that function analogously to endogenous carbohydrates, are being sought. The advantage of having such ligands is illustrated by the many roles of the protein DC-SIGN. DC-SIGN is(More)
