A novel chiral biphosphine ligands, 6,6-bis(diphenylphosphino)-5,5-biquinoline (BIQAP) was synthesized by two step reactions used optical pure BIQOL as starting material and the molecular structure of (R)-BIQAP has been determined by single-crystal X-ray diffraction.The ligand was utilized in Pd-catalysed asymmetric allylic allylations.High enantioselectivety was obtained in C-C and C-N bond formation of 1,3-diphenyl-2-propenyl acetate, with dimethyl malonate (up to 94.2% ee) and with aminations (up to 97.8% ee).
