Non-covalent interactions in the diastereoselective synthesis of cis-2,3-dihydrobenzofurans: experimental and computational studies

Abstract

The diastereoselective synthesis of 2,3-DHBs has been previously reported via an intramolecular Michael addition reaction using alkali bases such as Cs2CO3 and K2CO3. However, no systematic study has been performed to understand the possible role of bases in the mechanism of the reaction and factors behind the stereoselective outcome of the reaction. Herein, from experimental and theoretical points of view, we disclose the role of the cesium salt in the rate-determining step along the catalytic cycle and the key role of stabilizing non-covalent interactions in the stereoselective outcome of the reaction.
