Complexes of Ca2+ and Mg2+ with N-acetyl-α,β-dehydrodipeptides: The state in an alcoholic solution and its relationship with asymmetric induction upon diastereoselective hydrogenation

Article abstract of DOI:10.1007/BF02494633

In an alcoholic solution, N-acetyl-α,β-dehydrodipeptides interact with Ca²⁺ and Mg²⁺ ions to form complex particles containing several dehydrodipeptide molecules per metal ion. The composition of these particles and steric interactions in them determine the acidity of the carboxyl groups and the degree of asymmetric induction upon diastereoselective hydrogenation.
