    • New chiral phosphinopyrrolidine compounds of the general formula:
      wherein R¹ is hydrogen or -COA¹, -COOA², -CONHA³, -SO₂A⁴ or -PO(A⁵)₂, A¹, A², A³, A⁴, and A⁵ each represents independently alkyl or pharyl, R² is phenyl, di(lower-­alkyl)aminophenyl, lower-alkoxyphenyl or 3,5-dimethyl-4-­methoxyphenyl, and R³ is phenyl, lower-alkylphenyl, di(lower-alkyl)aminophenyl, lower-alkoxyphenyl or 3,5-­dimethyl-4-methoxyphenyl, with the proviso that R² and R³ may not simultaneously be phenyl, p-di(lower-alkyl)-­ aminophenyl or p-lower-alkoxyphenyl, as well as the use of these compounds as ligand for a metal complex catalyst for asymmetric synthesis of optically active compounds. The new chiral phosphinopyrrolidine compounds are useful ligands which attain both of high optical yield and high reaction efficiency in catalytic asymmetric reduction.
