A highly enantioselective hydrogenation of cyclic imines for synthesis of chiral cyclic amines has been realized. With the complex of iridium and (R,R)-f-spiroPhos as the catalyst, a range of cyclic 2-aryl imines were smoothly hydrogenated under mild conditions without any additive to provide the corresponding chiral cyclic amines with excellent enantioselectivities of up to 98% ee. Moreover, this method could be successfully applied to the synthesis of (+)-(6S,10bR)-McN-4612-Z.

Arene/Ru(II) complexes of (R,R)-N-alkyl-TsDPEN ligands are effective in the asymmetric transfer hydrogenation of ketones and imines in formic acid/triethylamine solution. The complex derived from the N′-Bn derivative of TsDPEN reduces monocyclic imines in up to 60% ee, whilst the N′-Me derivative of TsDPEN forms a more active catalyst than the non-alkylated analogue and reduces ketones in up to 97% ee.
