Selective Ester-exchange Reactions of Dibenzyl-aspartate and -glutamate in the Coordination Sphere of Copper(II) Ion

Article abstract of DOI:10.1246/bcsj.53.1564

Copper(II) complexes of the Schiff bases derived from salicylaldehyde and dibenzyl aspartate or glutamate have been prepared for the first time.Upon refluxing the solution of these complexes in methanol for 30 min, bis(α-methyl β-benzyl N-salicylideneaspartato)copper(II) and bis(α-methyl γ-benzyl N-salicylideneglutamato)copper(II) were obtained.The mechanism of these selective ester-exchange reactions in the metal-coordination sphere has been discussed.Several Schiff bases were obtained and characterized.
