Abstract
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 obtained using 1 mol% of [PdCl(η 3-C 3H 5)] 2 and 2 mol% of 3.
