Type [Co(dipeptidato)2] complexes (dipeptidato denotes dianions of glycylglycine, β-alanine, -L-alanine, and -L-leucine, β-alanylglycine and -L-alanine, L-alanylglycine and -β-alanine, L-leucylglycine, and L-prolylglycine) and the complex [Co(gly-gly)(L-pro-gly)]− were prepared by a method using lead dioxide as an oxidizing agent, and these complexes were separated into two diastereomers or enantiomers
[Co(dipeptidato)2] 型复合物(二肽表示甘氨酰甘氨酸、β-丙氨酸、-L-丙氨酸和-L-亮氨酸、β-丙氨酰甘氨酸和-L-丙氨酸、L-丙氨酰甘氨酸和-β-丙氨酸的二价阴离子,L -leucylglycine, and L-prolylglycine) 和复合物 [Co(gly-gly)(L-pro-gly)]- 以二氧化铅为氧化剂的方法制备,并将这些复合物分离为两种非对映体或对映体通过柱色谱法。光学异构体的绝对构型是根据它们在配体过渡区中的圆二色性图案确定的。
