To make a complicated recovering process of asymmetric di- or triamine compds. unnecessary after completion of the reaction by using an asymmetric diamine catalyst carried on a polymer expressed by a specified formula as the catalyst to be used for the production of org. compds. which have asymmetric carbon atoms in the molecules and which are useful for pharmaceutics and agricultural chemicals.

An asymmetric diamine catalyst carried on a polymer expressed by formula I having asymmetric di- or triamino groups fixed in polystyrene chains is used as the catalyst for various kinds of asymmetric reaction. Or, an asymmetric triamine catalyst carried on a polymer expressed by formula II is used. In formulae I and II, each of n and k is an integer 1 to 10, P represents a polymer chain and ≡ represents asymmetric carbon. The asymmetric diamine catalyst carried on a polymer is prepared from a copolymer of (S)-1-(4-vinylphenyl 1-10C alkyl)-2-(anilinomethyl)pyrrolidine such as (S)-1-(4- vinylbenzyl)-2-(anilinomethyl)pyrrolidine (1b), and divinylbenzene and styrene.
