Chiral N,N'-dialkylated cyclohexanediamine derivatives ligands have been synthesized and used in an asymmetric transfer hydrogenation of aryl ketones. Optically active alcohols with up to 93% enantiomeric excess were obtained in high yield.

A series of N1-methyl-1-phenyl-1,2-propanediamines substituted at the nitrogen (N2) by alkyl groups (CH3, C2H5, i-C3H7, t-C4H9) and the corresponding imidazolidines from formaldehyde have been synthesized.The study of their 1H- and 13C-NMR spectra allowed the differentiation of the diastereoisomers in these two series.
