IR characteristics of stereoisomers trans- bis- and mixed of copper(II) complexes with DL-threonine
By IR spectroscopy were studied of the trans- bis- and mixed of Cu(II) complexes [Cu(R')((±)-Thr)] 1-4a,a' (R' = gly (glycinate) (1a,a'), S-ala (S-alaninate) (2a,a') (±)-val (valinate) (3a,a'), (±)-thr (threoninate) (4a,a'), which include hydroxy amino acid - (DL)-threonine. It found that complexes 2-4 were obtained as diastereomers a:a' in ratio of 1:1 on the asymmetric carbon atom connected to the amino and carboxyl group.
