Abstract
π-Allylic substitution of allyl esters with sodium arylsulfinate was performed with an amphiphilic polystyrene-poly(ethylene glycol) (PS-PEG) resin-supported phosphine-palladium complex in water as a single reaction medium under heterogeneous conditions to give allyl sulfones in good to high yields. Catalytic asymmetric allylic substitution of cycloalkenyl esters also took place in water using a PS-PEG resin-supported chiral imidazoindolephosphine-palladium complex to give cycloalkenyl sulfones with up to 81% ee.
