Complexes of Ca2+ and Mg2+ with N-acetyl-alpha,beta-dehydrodipeptides: thestate in an alcoholic solution and its relationship with asymmetric induction upon diastereoselective hydrogenation
In. Lisichkina et al., Complexes of Ca2+ and Mg2+ with N-acetyl-alpha,beta-dehydrodipeptides: thestate in an alcoholic solution and its relationship with asymmetric induction upon diastereoselective hydrogenation, RUSS CHEM B, 48(5), 1999, pp. 895-898
In an alcoholic solution, N-acetyl-alpha,beta-dehydrodipeptides interact wi
th Ca2+ and Mg2+ ions to form complex particles containing several dehydrod
ipeptide molecules per metal ion. The composition of these particles and st
eric interactions in them determine the acidity of the carboxyl groups and
the degree of asymmetric induction upon diastereoselective hydrogenation.
