A study of chirally selective interaction in the stirred crystallization of glutamic acid and lysine is presented. The crystallization of S-glutamic acid is influenced by the presence of S-lysine but not R-lysine. Crystal nuclei in stirred systems are produced due to secondary nucleation. Secondary
Stirred crystallization of racemic (D/L)-glutamic acid (Glu) in the presence of small amounts of L-or D-lysine (Lys) was studied for the effect of transient chiral resolution by monitoring the time evolution of optical rotation and the concentration of the solution. The presence of a small amount of
Chiral asymmetry generation, the predominant production of one enantiomer in a non-chiral environment, could occur in the production of the chiral complex cis-[CoBr(NH 3 )(en) 2 ]Br 2 by the reaction of [Co(H 2 O) 2 {(OH) 2 Co(en) 2 } 2 ](SO 4 ) 2 with ammonium bromide in an aqueous medium. The main
