Abstract
Heterobidentate sulfide-tertiary amine ligands incorporating 1,2-aminothioethers derived from ephedrine and pseudoephedrine have been prepared and used successfully in the palladium-catalysed asymmetric allylic substitution reaction, giving ees of up to 89%. The stereoelectronic effects operating in the reactions are discussed.
