An enhanced stereoselective synthesis of α,β-unsaturated esters through the Horner-Wadsworth-Emmons reaction in deep eutectic solvents

A new scalable synthesis of ( E )-α,β-unsaturated esters has been developed using protic, non-toxic, and biodegradable deep eutectic solvents through the Horner-Wadsworth-Emmons reaction between triethyl phosphonates and (hetero)aromatic carbonyl compounds, encompassing electron-withdrawing and elec...
