Abstract
The bis-amino acid derivatives (+)-6 and (+)-8 were synthesised (>95% eel in mixtures with the corresponding diastereomers (dr:s 80:20 and 9 0:10, respectively) via asymmetric hydrogenation of the corresponding bis-didehydroamino acid derivatives using [Rh((R,R)-DIPAMP)(COD)]BF4 a s catalyst.
