Asymmetric hydrogenation of N-acetylhydrodipeptide complexes with Mg(II) and C(II) ions

N-Ac-Δ-Phe-AA form labile complexes with Mg(II) ions.Potentiometric titration data show that the carboxyl group of the dehydropeptide in them scarcely participates in complexation, unlike the complexes with Ca(II) ions.The hydrogenation of these complexes

Efficient 1,4-Asymetric Induction Utilizing Electrostatic Interaction between Ligand and Substrate in the Asymmetric Hydrogenation of Didehydrodipeptides

Electrostatic interaction between the amino group of the achiral 3-dimethylaminopropylidenebismethylenebis(diphenylphosphine) (1) and the carboxy group of the substrate enable an effective 1,4-asymmetric induction in the RhI-catalysed hydrogenation of didehydrodipeptides, to give (S,S)-or (R,R)-products selectively.The selectivity reached up to 94percent diastereoisomeric excess with acetyl didehydrodipeptides and 92percent with benzyloxycarbonyl substrates.
