Abstract: A chiral bidentate phosphine, 2, 3-isopropyldene-1, 4-bis((diphenylphosphino)amino)bu-tane derived from L-(+)-tartaric acid has been obtained. The rhodium(Ⅰ)-complex of thisligand with(Rh(COD)ClO4)in the asymmetric hydrogenation of three derivatives of α-aceta-midoacrylic acid gives 10.4-25.6% optical yield.

Key words: diphosphine, asymmetric synthesis, catalyst, hydrogenation, rhodium complex
