Diastereoselective SmI2-mediated cyclisation of δ-oxo-α,β-unsaturated esters to cyclopropanols
Villar, Hélène,Guibé, Fran?ois
, p. 9517 - 9520 (2007/10/03)
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.
