A divergent synthesis of (−)-4-epi-shikimicacid 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-shikimicacid via conjugate addition of a thiol occurs in high diastereoselectivity to afford a product with the features of fucosylated glycans
