Diastereoselective SmI2-mediated cyclisation of δ-oxo-α,β-unsaturated esters to cyclopropanols
摘要:
In the presence of samarium diiodide and a proton source, delta-oxo-gamma,gamma-disubstitutcd-alpha, beta-unsaturated esters readily cyclise with complete diastereocontrol to give anti-cyclopropanol products. (C) 2002 Elsevier Science Ltd. All rights reserved.
