Enantioselective preparation of 8-oxabicyclo[3.2.1]octane derivatives via asymmetric [3+2]-cycloaddition of platinum-containing carbonyl ylides with vinyl ethers

A catalytic asymmetric synthesis of 8-oxabicyclo[3.2.1]octane derivatives was achieved through the [3+2]-cycloaddition of the platinum-containing carbonyl ylides generated from acyclic γ,δ-ynones on treatment with 10 mol % of PtCl₂-Walphos and
