General description

(±)-trans-1,2-Diaminocyclohexane is widely used as a ligand in coordination chemistry and organocatalysis. It also serves as an achiral ligand in asymmetric catalysis. (±)-trans-1,2-Diaminocyclohexane was condensed with aliphatic dialdehydes to form [3+3] or [2+2] macrocyclization products.

Application

(±)-trans-1,2-Diaminocyclohexane was used in the synthesis of macrocyclic [3+3] hexa Schiff base. It was also employed in the synthesis of multidentate ligands, chiral auxiliaries and chiral stationary phases.

Aliphatic dialdehydes of rigid structures having a cyclohexane, a bicyclo[2.2.2]octane or a [7]triangulane skeleton, have been condensed with enantiomerically pure trans-1,2-diaminocyclohexane to give [3+3] or [2+2] macrocyclization products.
