Diastereoselective conversion of chiral imines of the formula I to amines of the formula II
where the R
1
to R
4
radicals are each as defined in the description and R
1
and R
2
are different than one another, by converting the imine of the formula I in the presence of hydrogen and a heterogeneous copper-containing catalyst.

Diastereoselektive Umsetzung von chiralen Iminen der Formel (I) zu Aminen der Formel (I), (Il) wobei die Reste R1 bis R4 die in der Beschreibung gegebene Bedeutung haben und R1 und R2 voneinander verschieden sind, indem man das Imin der Formel (I) in Gegenwart von Wasserstoff und einem heterogenen Kupfer-haltigen Katalysator umsetzt.
Asymmetric reduction of enantiopure imines with zinc borohydride: stereoselective synthesis of chiral amines

The first application of zincborohydride in the reduction of enantiopure imines for the stereoselective preparation of both the enantiomers of secondary amines is described. A possible explanation of the stereoselectivity and of the reaction mechanism is suggested on the basis of theoretical calculations.
