Abstract

Abstract β, γ-Unsaturated esters with stereodefined trisubstitued C= C double bonds were prepared by the Arndt–Eistert homologation of α, β-unsaturated carboxyl halides, by two- step methoxycarbonylation of allylbarium reagents, by deconjugation of α, β-unsaturated esters, and by Horner–Wadsworth–Emmons variants of the Stobbe condensation. Sharpless asymmetric dihydroxylation of the β, γ-unsaturated esters, followed by spontaneous ...
