The synthesis of aromatic dicarboxaldehydes, using dilithiation methodology is described along with their reactivity, in the [3 + 3] cyclocondensation reaction, with (1R,2R)-diaminocyclohexane to give trianglimine macrocycles. The scope and limitations of the cyclocondensation reaction are studied and some comments
