New chiral ligands, phosphinooxathianes 3 and 6, were synthesized easily and their ability as ligands were examined in Pd-catalyzed asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate to give an allylation product. Enantiomeric excess of up to 94% has been obtaine
