Abstract

NEW MATERIAL:The titled ligand expressed by formula I (R is aliphatic, aromatic or organic sulfonyl group;* is optically active site).
EXAMPLE: (2S, 4S)-(N-Phenylcarbamoyl)-4-diphenylphosphinomethulpyrrolidine.
USE: An asymmetric catalyst for preparing optically active α-amino acids having a high crystallinity, good handleability and a very high optical yield.
PROCESS: An optically active pyrrolidinodiphosphine expressed by formula II is reacted with an isocyanate expressed by the formula R-N=C=O to give the compound of formula I.
