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

Autor: A. S. Peregudov, I. N. Lisichkina, T. A. Larina, T. Yu. Vasil'eva, V. M. Belikov

Publikováno v: Russian Chemical Bulletin. 48:895-898

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 deter
