The degree of the optical activations of racemic α-substituted carbonyl compounds <I>via</I> the formation of optically active immonium salts and the subsequent hydrolysis were largely affected by acids used for the hydrolysis of the enamines. The ratio of the diastereomeric immonium salts depends on the temperature. There is a relationship between the configuration of the optically activated carbonyl compounds and those of amines used. These suggest that the optical activation is due to the asymmetric transformation.
