Article abstract of DOI:10.1016/S0040-4039(00)95194-3

Solid-liquid phase transfer catalysis (PTC) without added solvent efficiently promotes chiral Michael addition when the reaction is achieved in presence of quaternary salts derived from (+) or (-) N-methyl ephedrine. enantiomeric excesses are significantl
