Abstract
trans-1,2-Diaminocyclohexane has been used as the backbone of the chiral macrocycles of amido- and amino-ferrocenophanes. Planar chirality was introduced via a self assembled amide-directed diastereoselective ortho-lithiation. Detailed NMR analysis revealed the (Rp)-configuration in the newly synthesised compounds.
