Hydrogenation of nitrobenzenes bearing aldehyde-containing substituents over heterogeneous platinum or palladium catalysts gives medium and/or large heterocyclic amines as a result of simple or dimeric cyclisation in moderate to good yields; a range of heteroatoms can be incorporated into the macrocycles, enhancing their potential as ligands.
