Diastereoselective SmI2-mediated cyclisation of δ-oxo-α,β-unsaturated esters to cyclopropanols

In the presence of samarium diiodide and a proton source, δ-oxo-γ,γ-disubstituted-α,β-unsaturated esters readily cyclise with complete diastereocontrol to give anti-cyclopropanol products.

Investigation of SmI2-mediated cyclisation of δ-iodo-α,β-unsaturated esters by deuterium 2D NMR in oriented solvents

We have investigated the mechanism of the SmI2-mediated cyclisation of δ-iodo-α,β-unsaturated esters using proton-decoupled deuterium 1D and 2D NMR in weakly ordered polypeptide liquid crystal solvents. Analysis of the spectroscopic results dem
