trans-1,2-Diaminocyclohexane is an organic compound with the formula C₆H₁₀(NH₂)₂. This diamine is a building block for C₂-symmetric ligands that are useful in asymmetric catalysis.^[1]

A mixture of all three stereoisomers of 1,2-diaminocyclohexane is produced by the hydrogenation of o-phenylenediamine. It is also side product in hydrogenation of adiponitrile. The racemic trans isomer (1:1 mixture of (1R,2R)-1,2-diaminocyclohexane and (1S,2S)-1,2-diaminocyclohexane) can be separated into the two enantiomers using enantiomerically pure tartaric acid as the resolving agent.^[2]

Oxaliplatin, a complex of R,R-diaminocyclohexane, is an important anticancer drug.

Derived ligands

Representative ligands prepared from (1R,2R)- or (1S,2S)-1,2-diaminocyclohexane are diaminocyclohexanetetraacetic acid (CyDTAH₄), Trost ligand, and the salen analogue used in the Jacobsen epoxidation.
