The syntheses of new chiral pyrrolidinephosphine ligands (4,5,6) and their applications to the catalytic asymmetric syntheses of some chiral natural compounds were discussed. Thus, optically active α-amino acids (8) (83-91% optical yields), salsolidine (14)(45%), pantolactone (18)(86.7%), β-amino acids (23)(55%) and a-methylsuccinic acid (25)(94%) were attained in almost quantitative yields.
