Difficult-to-access chiralprimaryamines were formed in good to high yield and ee using a rare example of a one-potsynthesis from prochiral ketones (sequentialreductive amination-hydrogenloysis). As a highlight we also demonstrate a one-potreductive amination-hydrogenolysis-reductive amination (five reactions) of ortho-methoxyacetophenone resulting in the chiral diamine 1-(2-methoxyphenyl)ethy
